Also, for different types of terrain and climates, such as humid, arid, hot, cold areas, fields, rivers, mountains, beaches, jungles, forests and even in the city.



What is a metal detector?

Let's start with the first thing, you know exactly, what is a metal detector? I bet so, but we want to make sure we explain it to you as the Royal Academy of the Spanish Language would do it or as Garrett himself would, that is, with all his specifications.

‟A metal detector is an electronic equipment that by transmitting an electromagnetic field can detect metallic objects.
This electromagnetic field or electromagnetic impulses have their start from the coil towards the ground. The objects that are in that electromagnetic field are energized and retransmit their own field, in this way it is that the detector manages to reach its objective. "

And you wonder, how is it that they always detect valuable objects? Well, almost all detectors are capable of discriminating between different types of objects and metals. In addition, they can be adjusted to ignore unwanted objects, making you always get something truly valuable in your searches, completely guaranteeing your investment.

And if you are also wondering what the detectors look like, here we explain it to you, although they do not all look the same, most retain the same structure, to ensure a good functioning of the metal detector.

A metal detector is an object with an elongated handle and handles, with a flat plate-shaped surface where the sensor is located with electrical current.

From said '' plate '', an electric current is sent to the ground, but when a metallic object is in the perimeter of the current, it is distorted and emits an alert sound, warning that there is a metallic object in that space and what time you got down to work and start digging!

The first uses of these metal detecting machines were specifically for the military industry, since they detected the presence of land mines, anti-personnel mines or any other explosive system that had metal.

Of course, as you already know, today its use is so common, that it is used by experienced archaeologists to amateurs who have fun searching for treasures with metal detectors and at the seaside.

Its main function is to find hidden metal elements. Of course, there are different ways of use and each model has distinctive specifications for each metal hunting activity.

A metal detector can be used in security systems for the search for dangerous metal artifacts such as weapons, in the search for mines and in the search for treasures, to detect from old coins to gold nuggets.

So, no matter what use you are going to give it, it will still work correctly if you are looking for the detector that best suits your needs, if you are an experienced metal finder, a beginner, an archaeologist or a fan of collecting objects, we have the detector for you.



How does a metal detector work?

Now that you know scientifically what a metal detector is, you will want to know how they work because as we already taught you in the preamble, everything is magnetism.

The detectors transmit an electromagnetic field from the coil to the ground, and since every metallic object within said field is energized and retransmits its own electromagnetic field, the coil receives the retransmitted field and will alert you to what depth the object is.

Not to mention that its discrimination capabilities are quite good, so you will not take home garbage, but rather some treasure no matter how big or small it is.

The magnetic field is the matrix of the operation of these machines, therefore, we will show you how this magnetic field is created.

The magnetic field attracts ferromagnetic materials making the whole process possible. Inside the detector plate, there are 2 coils of wire wound in a spiral on a core, these are called the transmitter coil and the receiver coil.

The transmitter coil is the conductor of an inverted current flow thousands of times per second, creating a working frequency and in turn originating an electromagnetic field capable of penetrating the earth and the receiving coil is capable of detecting the variation of this field. by the presence of any metal.




Types of Detectors

Now that you know how to use a metal detector, now we will show you how they are classified according to their way of working and their frequency, read on to find out their differences and which one is best for you.

VLF Low Frequency Detectors - These are the most frequently used. Their working frequency is one or two, being much more sensitive to copper and silver, in addition they perfectly combine different factors such as discrimination, high sensitivity, ground balance and a great depth of detection.

However, one of their major drawbacks is that they do not have much stability or good performance, since the mineralization of the land where they will be used affects their operation.

Multifrequency detectors - These are also low frequency detectors, since they use between 17:28 frequencies for their search, and most decide to work with this system under frequencies between 1.5 and 25 or 100 Khz, thus improving their stability and performance. , although it is in a highly mineralized terrain.

PI Pulse Induction Detector - These are mostly recommended in beach searches or in places where there is not much presence of scrap metal, since they do not have a good discrimination system, adding their low search autonomy.

Each pulse requires a large amount of energy, despite all this, it has great qualities, its great sensitivity and depth, and the best thing, that, despite the mineral conditions of the ground, these do not alter its performance.

These types of detectors have a great capacity to handle highly mineralized ground conditions and their ability to detect objects at considerable depth.

Box or antenna detectors - This type of detectors use a transmission and reception system, and this entire system works thanks to the perpendicular position of the coils and the distance that separates them, which is about 70 cm.

Its main qualities are that it can distinguish ferrous and non-ferrous metals.

But they are also not very sensitive to small objects and their operation can easily be influenced by the elements of the terrain where they are used. These detectors do not have a great capacity for discrimination, so it is a bit more complex to work with them.

Gold detectors

In the mid-nineteenth century, prototypes of metal detectors began to be made and although at first it was only used for common metals or for war operations, little by little it became an alternative to search for metals, treasures, jewelry and metal most precious of all, gold.

Just a few years before the invention of the metal detector, in the 1840s, the gold rush broke out, where thousands of people moved to the golden lands of the western United States in search of large quantities of gold.

Although this happened years before the forerunners of treasure detectors began to explore, I don't mean that people wouldn't be interested in how to search for gold with a metal detector.

Many, many people saw in these devices to search for gold the opportunity not only to make a lot of money, but to become a collector of really valuable objects by searching for gold with a metal detector.

However, this did not happen until several years after the invention of these machines, as they were previously used for warfare.

Unlike the search for treasures, coins, jewels or relics, the search for gold cannot be left in the hands of any team, with the help of our experts, you must select the correct equipment since the search for gold requires careful study .

Whether it's pieces, whole objects, or gold nuggets, metal detectors always detect gold.

Modern detectors have the ability to discover gold in extremely small sizes, such as the size of a grain, although as the size of the object is larger, it is easier to find them deeper.

Usually, the gold detectors are of the type of low frequency VLF circuits, which are very sensitive to gold, although also to the minerals in the ground, even so, their adjustment allows to filter most of the mineral interference.

The Pulse Induction type of low frequency circuit, which ignores all mineral soil conditions and has the ability to find large amounts of gold at great depths, making the decision of the best metal detector for gold quite difficult. .

If you are wondering which is the best metal detector to look for gold, I will tell you that, with almost all our detectors, you can look for gold, we will show you its differences and virtues in the search for gold, from the best quality to the gold detector special price, all for you:

Where to use your metal detector?

You can imagine that valuable objects such as treasures, relics, coins or gold are found anywhere in the world, and it is like that, in almost all the world there are buried treasures scattered in different lands.

But in some places there are many more possibilities to find these treasures and where you can start exploring without problems, in the following text, you will know where to look with a metal detector.

Ghost towns: If you find yourself in a settlement or some abandoned city, then run and go for your treasure detector, as these are very good places to start detecting metals.

Some ancient mining towns and settlements have hidden treasures and valuable items waiting to be unearthed. So the chances that you will find at least some ancient coins and other historical items are very high.

Gardens: Have you ever been curious about what things can be hidden in your home's garden or in your neighbor's? If so, then you should also go for your detector and start exploring without even leaving your comfort zone.

Tons of things may be waiting under your garden and the older the ground, the better your chances of finding something valuable.

They are areas that can host a significant number of people over time. Which means that something lost is most likely buried there. These odds increase if the garden is old or attached to a place that has history.

In places like these, you could find everything from coins and toys, to relics and jewelry, which makes the gardens an excellent place to use your metal detector.

Beaches: Beaches are usually the favorite places to use metal detectors, and if you know how, when and where to detect metal on the beach, you can collect a large number of valuable items.Searching for treasures along the coast can cause you to discover many great items.

And we will tell you a few secrets that you will thank us for, the best moments to detect on the beach are, after a storm or after sunset and when the bathers have left the seashore, leaving coins, jewelry and other interesting items lost.

The beach is a very good place to look for coins with a metal detector. Using a detector on the beach has the great advantage that it almost always guarantees that you will find something and that something will almost always surprise you!

Squares and courtyards of the churches: These places are almost always full of history and tend to be many years old. The oldest constructions in a city or town are churches and squares since, in general, it is the first thing that is built when a community is installed.

Therefore, many may be hundreds of years old, which is why these places are a paradise for treasure hunters and relics.

Fields: The fields are often full of treasures and artifactsEspecially where farmers work, they are an excellent starting place for metal detection, because the surface of these fields is constantly changing by external factors, the elements come close to the surface and can be easily detected when you search.

Of course, before detecting any property, you must ask the land owner for permission and make sure that, in that place, it is legal to search with a metal detector.

How the history of metal detectors began

The nineteenth century is known for being a time when the world stopped being only agricultural and livestock to become an industrialized society thanks to the many discoveries and the force exerted by large industries and companies in society.

One of the discoveries that significantly changed the world was the invention of electricity, which brought with it many more experiments, discoveries and economic items.

Right after this, many academics, scientists and miners began to develop metal searching machines that were capable of locating metals buried underground, as they realized that underneath them they could find endless treasures and relics of great value.

There are still some debates as to who was the true inventor of the metal detector, since the history about it is not very clear, but one of the first feats of these devices took place in the 19th century, when the president of the United States United, James Grafield suffered an attack in July 1881 in Washington DC, by Charles J. Ghuiteau.

The wound was not fatal since the shot was in the back and it did not seem such a deep wound, however, as much as the doctors searched for the bullet and used dozens of treatments to stop the infection, they were unsuccessful.

At that time, Alexander Graham Bell enjoyed great popularity thanks to the invention of the telephone, for which he was a regular visitor to the White House and luckily, had been testing a prototype metal detector with soldiers of war that housed bullets in his body, having very good results.

For which he was called urgently to help the White House doctors find the bullet, which they did for days with the device, which was buzzing for hours, but unfortunately it did not yield any results, despite its effectiveness. been tested in previous tests.

Can you believe that the reason the detector didn't find the bullet was because the bed the president was in had metal springs?

Something very rare at the time and that nobody noticed. Well, as you may already know, the metals around our target can confuse the machine and hinder the search as it happened in this case, and as you may have already guessed, President Garfield died from his infected wound on September 19, 1881. .

And although in this story the detector did not obtain the expected results, this put the metal detectors under the spotlight, because in many other tests (in which there were no spring beds) the results were successful, being very helpful in the tests. wars.

This Bell prototype was the starting point for the true evolution of these machines, which at first were excessively large, complex and difficult to use, but which, without a doubt, were of great use especially to find mines and unexploded bombs later of the First and Second World War.

One of the earliest metal detectors was made of wood with some crudely assembled cables and tubes, which served as inspiration for many manufacturers.

The person who holds the first patent for a metal detector is Gerhard Fisher in 1925, who also began to market them to create an empire with these machines.

Examples later followed by manufacturers like Charles Garrett or White's, these names seem familiar to you, right? Well, they are the same manufacturers that today you get in Dadco Technology Peru, with a great track record of quality and good results.

Like many inventors, Fisher was looking for one thing and got another, as he was doing his work on navigation systems when he discovered that the radio waves he used were distorted by the minerals in the rocks, which is why I suspect that this same technology, but in a reduced scale could work like a metal detector.

The electrical engineer Garrett also perfected the metal detector, as it became his hobby but he couldn't use it the way he wanted, and instead of continuing to search the market, he decided to get down to business and forever revolutionize the metal detector industry. the metal detectors .

Like them, many others have also perfected and contributed to the evolution of these machines such as John Bardeen, William Shockley and Walter Brattain, who not only focused on the detectors, but also developed coils, discriminators and other elements that help the operation of the detectors. .

Throughout the 20th century, the metal detector evolved significantly and went from being a machine used to detect explosive systems or landmines, to becoming a daily routine and a hobby for many.

With each decade it became more effective and precise, as well as its dimensions were reduced, making it much more manageable and easy to use for anyone and not only professionals, but amateurs and beginners, even children.

These days, detectors have a sophisticated technology that allows them to measure the depth and position of the metal and one of the most useful things, to know what type of metal we are going to find.

The companions of metal detectors

Metal detector accessories are the perfect complement, because thanks to these accessories the search for metals can be much easier, faster and more successful.

Let's start with the great coils, which are a clearly necessary complement to metal detectors , the so-called eyes of detectors, they are like a kind of lens of a photographic camera, so, without the coils, our detector '' would be blind '' '.

The coils are a flat circular disk sensitive to metal objects in a close space, they create an electromagnetic field and when an object is inside it, a distortion is generated which is then sent to the control box to notify us of the finding.

Another accessory is the headphones, these not only serve to listen to the alert by the detector when having found something, they also serve to protect the ears, since they minimize the sound so that it is emitted in a wave that does not damage the ear canals.

Not to mention that they are extremely light and easy to handle, with just one button you can configure them to your liking. Its use is specifically so that the detection alert signal is not distorted at any time.

The trays are another great accessory, they are exclusively designed to pan for gold easily and quickly, they have a spiral-shaped plate that also facilitates the search for gold and the best thing is that despite their great functionality, they have a real price accessible.

Let's talk about Coils

A coil is a flat regular disk, which generates a magnetic field sensitive to metallic objects near it. It is located at the end of the bar and is connected to the control box by means of a cable that wraps around the bar.

The shape and size of the coil is what determines the size and depth of the magnetic field. These coils come in different types of sizes and specific to each search activity, so here we will show you which coil is best for you.






How to know which is the ideal coil?

The ideal coil can be obtained according to the search activity you are going to perform, the environment in which you use it or the detector, but everything in the coils depends on their shape and size.

For example, elliptical coils are more maneuverable than circular ones and also offers greater coverage because it is more elongated. Even so, circular coils have more sensitivity and depth of detection, which is why they are the most widely used.

‟If you want to be completely sure that you are carrying the right coil, everything lies in its diameter and shape, since the size of the electromagnetic field derives from there, and therefore the depth and sensitivity of detection”

That is why here at Dadco Technology Peru, when you take a coil home, you also take the knowledge and personalized advice of our metal detection experts, since thanks to their professionalism they will guide you to choose the coil that best suits your needs. your needs to achieve positive results.

If you want to search for coins or gold nuggets, the size of the coil should be small, but if you want to search for much larger treasures, the coil must be large so that the magnetic field expands.

Likewise, as the size of the coil increases, the field of view becomes less concentrated and it stops detecting small objects, showing that the size of the coils should be an aspect that we must take into account when choosing one.

Coils play practically the most important role in the metal detector, the indicated coil depends on the environment in which you are going to use it, in addition to the ground conditions and the search method.

The ideal metal detector for you

The choice of the first detector is something very serious, because it will accompany you on your first adventures and with it you will make your first find, something you will never forget, then we will guide you about which metal detector to buy.

Likewise, if you already have a collection of detectors and you are a regular search engine, it is also very important to choose the detector that you now need well, since, depending on the terrain or type of search, each detector has different characteristics, specifications and functions.

Beginners: The beginner models are usually inexpensive and easy to use, as they are specifically created for people who are new to the world of metal detectors, however, they are totally professional and their quality is as high as that of more detectors. expensive.

If you are a beginner, the ideal detector for you is the White's Coinmaster , this is a small metal detector that works with a 9 '' search coil and is so great that it guarantees a very good operation despite its low cost.

One of its best features is that its discrimination is very good, making it detect only valuable elements and completely discard scrap, in addition to all that, it is waterproof!




For the little ones: Metal detectors are the perfect gift for children, as it stimulates their curiosity, encourages them to explore the outdoors, developing their creativity and independence, in addition to becoming interested in history and archeology, so Which, having a metal detector is something you will appreciate over the years.

The metal detector for children, par excellence, is the XVenture of the White's brand, this detector ensures fun in every search, specially made for children over 7 years old.

She has been creating fun and unforgettable moments in children's lives and family searches for years, after all, what child wouldn't want to find a lost treasure?





Gold rush: All metal detectors can find gold, but if you are specifically one of those gold fans, you will want a detector that stands out for its effectiveness when looking for gold, be it nuggets or larger pieces.

The GMT is one of the best metal detectors that detects gold, making it an option that no one regrets when acquiring it.

The house's recommendation is GMT, White's GoldMaster , this device ignores the other minerals in the ground and focuses on finding nuggets and coins, both large and small. Its frequency is 48 KHz and its coil is waterproof to allow searching in rivers.





Mountainous areas: Most explorers choose mountains to search for treasures, since they can have a lot of archaeological history, therefore, the sierra is one of the best places to search for metals.

Most of our detectors perform well in the mountains, but specifically the Garrett GTI 2500 "Eagle Eye" shows great performance in mountainous areas.

It is a gold detector that will not waste time, since its discrimination system is so advanced that it immediately identifies whether the object is valuable or junk. It is more specifically a coin detector.






Beach, sun and sand: Seeing explorers with their metal detector at the seashore has been quite common for some time, and if so many people do it, it must be because it brings good results, right?

Metal detection on the beach has become very popular over the years and has become a fairly common hobby, and although beach detection does not require such expensive and complex equipment, it does require a detector that complies with high expectations.

And that's it, the Garrett brand ATX DEEPSEEKER, built to a durable military-spec design, featuring advanced pulse induction technology, extremely sensitive DD coil for detecting gold parts and gold nuggets, large and small.







What is the best metal detector?

You will wonder which is the best metal detector on the market, then let me tell you that the best is the one that suits your needs, because if it is true that some detectors have better technology, more specifications and a greater number of findings.

Even so, the type of terrain you will work on and what type of use you will give your detector is very important. If you want to find coins, lost artifacts or gold nuggets, as they say, for every occasion, we have a detector.

Our best brands of metal detectors, have very recognized names, such as White's, Garrett, Fisher or Nokta Makro, all these brands have years of respected experience and research so that the detectors are increasingly effective and easier to use.

Great finds made with a metal detector

You may think that a metal detector will only be able to detect coins or some buried valuable objects, but we will show you that you can achieve much more than that, there is a universe of hidden treasures in front of our eyes and people like the protagonists of the following stories are witnesses of that.

A hobbyist, David Booth acquired a metal detector and in less than a rooster crows he found 4 buried necklaces, with nothing more and nothing less That 2 thousand years old! One of the most important treasures found in Scotland.




The explorer Dennis Holm, discovered a small gold cross in a Danish field, it is a representation of Jesus Christ on the cross. After consulting an expert, Holm discovered that the cross is from the 10th century, made entirely of gold found with a metal detector.


An intentional discovery caused the media to turn their attention to René Schön and his student Luca Malaschnitschenko, just 13 years old!

Two archeology enthusiasts who were exploring by chance found a buried treasure consisting of rings, brooches, necklaces, braiding, pearls, coins and even a Thor's hammer, from Denmark dating from the year 958.


Garrett metal detector, a great option

The Garrett metal detector company, has since 1964 been one of the most respected and with more experience thanks to its excellent quality and affordable costs, since Garrett detectors offer high-level quality, but for prices much lower than metal detectors. higher ranges.

The best metal detectors on the market for professionals and amateurs


Did you know that if you find a treasure on public property, you are entitled to receive 50 percent of its value? A metal detector is what you need to do it

Using a metal detector on the beach or in the field can become a pleasant hobby that leads us to find coins, jewelry and even treasures hidden for a long time. A reward in the form of gold, silver or any other precious material that will make us feel like Indiana Jones himself.



How to choose a metal detector and what aspects should you take into account before buying one?
Before diving headfirst into an offer on metal detectors, we must consider the following aspects:

  • 1. The type of coil : there are low or high frequency, pulses, etc. This aspect marks the type of detector we are in front of and the use for which it is focused. In the section 'What is a metal detector for and how does it work?' we explain each one in detail.
  • 2. The size of the coil : the larger it is, the more ground we will cover per pass and with greater precision we will be able to locate small objects.
  • 3. What is our level ? Frequency bump oscillator detectors and low frequency detectors are recommended for beginners . Instead, pulse and high frequency metal finders are suitable for advanced users and professionals .
  • 4. On land and / or in water : the best metal detectors to hunt for treasure underwater are pulse detectors . We must ensure that all its components are waterproof if we are going to use ours in a river or in the sea.
  • 5. Battery capacity : the larger it is, the longer we can use the device. Of course, this aspect greatly affects the price of the metal detector. A good option is to choose a model with reduced autonomy but whose battery is interchangeable and always carry a spare.
  • 6. The length of the stem : the ideal is that the stem is extensible so that it adapts to our height. It must also be foldable to be able to transport it comfortably while we are not using it.
  • 7. Display - Based on reviews on metal detectors reviewed here, this is a vital element. For this reason, we recommend choosing a coin and gold finder with an LED display that serves to accurately indicate the position of the object .
  • 8. Loudspeaker and headphones : a loudspeaker with light tones will help us to locate the metallic object at first. Of course, we must make sure that the underground metal detector has a universal headphone jack so that we can use any model we have at home instead of buying a specific one.
  • 9. Ergonomic design : the stem must join the forearm with the coil plate as an extension of the hand . Only then will we have perfect mobility.
  • 10. Extras : a metal detector with night vision screen, with detection indicator and adjustable depth will allow us to find valuable objects more comfortably. If you have a volume detector, we will also know the size of the treasure found to identify it quickly.

What is a metal detector and what can I find with it?

Metal detectors are manual and portable electronic devices that, thanks to the emission of electromagnetic pulses , are capable of detecting the presence of metal objects buried underground or underwater . Traditionally, they have been used in mines and in archaeological excavations, although many people have joined the 'hobby detection' craze and search for hidden treasures on beaches and similar places.

With a metal detector it is possible, for example, to search for coins, rings, earrings or any piece of silver, gold or similar precious metal jewelry lost in the sand or on the ground. They are even used to find gold nuggets in rivers, although for this it must be a waterproof metal digger.

What is a metal detector for and how does it work?

A powerful metal detector will allow us to find any metallic object located at a certain depth in the ground. This will depend on its greater or lesser sensitivity . Moreover, the best metal finders of the moment are able to discriminate between non-interesting ferrous elements (a nail, a screw ...) and others that are (gold, silver, copper, etc.). The best metal prospectors of the moment discriminate the elements that do not interest us from those that really do, such as gold, silver or copper For this, the metal finder has a plate in its lower part and inside which a piston coil is housed . This, when powered by a battery, emits an electromagnetic field to the ground in order to 'energize' the hidden metal objects. In doing so, these objects start to emit their own electromagnetic field . This is detected by the standard search coil, which is responsible for alerting the user through an acoustic or visual signal. We can distinguish the following types of metal detectors :

  • 1. Frequency Bump Oscillator (BFO) Metal Detectors : These are the cheapest and most basic metal finders . They are very easy to use, but they do not discriminate between types of metal.
  • 2. Pulse Induction (PI) Metal Detectors: These are the recommended metal detectors for fresh and salt water . They offer various sensitivity settings and are not altered by ground mineralization.
  • 3. Low Frequency Metal Detectors (VLFs) : The best value for money metal finders . They are cheap and discriminate between ferrous and non-ferrous objects, although they are adversely affected by the mineralization of the ground.
  • 4 . High Frequency (HF) Metal Detectors - These are modern, intelligent and highly sophisticated treasure hunters . They are capable of detecting even minute metal particles, which is why they are commonly used in the search for gold in rivers and mines.
  • 5. Pinpointer metal detectors : these are short-range devices complementary to the main detector . They serve to accurately locate a very small object when we are unable to do so with the search engine.

Where can the metal detector be used in Spain?

It depends on the case. In Spain there is no national legislation that specifically regulates the use of metal detectors, so this issue is left to the autonomous communities . For example, in Andalusia its use is totally prohibited . We will have to consult the current regulations in our place of residence to clear up doubts. In any case, it is prohibited to use metal detectors without obtaining the relevant permits in the following places :

1. Mineral and archaeological surveys .
2. Fenced farms of public or private property although their doors are open.
3. Nature reserves, places of historical interest, archaeological areas and assets of cultural interest .

That said, the use of metal detectors in our country is relegated to beaches, land belonging to farms that we own or natural outdoor areas that are not fenced . But can they give us a metal detector fine ? Yes, and quite important if we use it in any of the places mentioned above or if the authorities understand that we have attacked or tried to loot objects that can be considered historical heritage. For example, in Andalusia, fines of up to 120,000 euros have been imposed on people who have found and tried to steal an object of value found with a device of this type.

What do I do if I find a hidden treasure?

Finding a treasure is the dream of any metal detector user. Specifically, they can only be considered as such "unknown or hidden deposits of jewelry, money or precious objects without legitimate belonging" ( Article 352 of the Civil Code ). According to article 351 of the Civil Code , the hidden treasure is the property of the owner of the land on which it is located . If it does not appear in a private property but in a public one, it will be the State that is considered as the legitimate owner . However, its discoverer is entitled to receive 50% of its value . However, if the treasure found was of interest in an artistic or scientific field , the State will carry out an appraisal and will automatically acquire it . Of that price, he will pay 25% to its discoverer and another 25% to the owner of the farm where it was found.

Metal detector rental. It's possible? Where?

Renting a highly sensitive professional metal detector to search for gold and other precious metals is not the most common, but it is possible. Many stores specializing in the sale of this type of device offer the possibility of using them for one or several days for a reasonable price . For example, in the surroundings of Madrid and next to many beaches in the Valencian Community and Barcelona it is possible to find premises and positions specifically dedicated to this task. If we find a treasure in a public property, the State will be considered the rightful owner and the discoverer will receive 50% of its value Without a doubt, this is a very interesting option for those who want to use one of the best possible high-precision metal detectors for a short period of time to cover a terrain where they suspect that there may be a treasure without having to make a large investment in your purchase.

Useful accessory for your metal detectors

Even the best metal detector requires a series of accessories so that we can get the most out of it:
  • 1. Carrying bag : to be able to carry the search engine anywhere comfortably.
  • 2. Earphones or headphones : allows us to eliminate external noises to listen to the sounds emitted by the targets located deeper.
  • 3. Shovel : with it we can easily dig into the ground.
  • 4. Location probe : it will allow us to obtain a more precise location of the object.
  • 5. Finding bag : here we can put the valuable and delicate objects that we find with the guarantee that they will not deteriorate during transport.


What is and how does the all metal mode and the disc mode work on metal detectors?
Most likely, a cheap metal detector will only have 'all metal' mode. However, a more advanced one will also include a 'disco' mode. In this they differ:

1. All metal mode : they emit an electromagnetic field capable of detecting all types of metals, that is, without any discrimination.
2. Disc mode : not all metals are 'energized' in the same way after receiving the electromagnetic pulse from the metal detector. Models equipped with this system discriminate between valuable metals (silver, gold, platinum, titanium, copper ...) and others with no apparent value (iron, zinc, steel ...). Recommendations for better use in metal detectors After buying a gold and metal detector in general, we must follow these tips to use it correctly:

  • 1. Place the coil plate between 3 and 5 cm from the ground .
  • 2. If we do not have a submersible metal detector with a waterproof coil, never put it in water.
  • 3. On the other hand, if it is submersible, we only have to introduce the coil plate and the extendable stem without reaching the LED screen.
  • 4. We must be very careful not to hit the coil as it is the most delicate part of the device.

Metal detectors for children

Metal detectors for children are identical devices to those designed for adults but have a number of special features to better suit them. For example, their size is smaller and they are much lighter . Its detection functions are also less varied since they are focused on a purely recreational use . However, they have a robust construction to withstand the hustle and bustle that they will be subjected to by the little ones.

Top brands of metal detectors

Without a doubt, the best brands of metal detectors according to the opinions analyzed in this comparison are the following:
  • 1. Orcrom : a company with more than 20 years of experience that has both industrial and professional metal detectors as well as treasure hunters for amateur users . It also has a wide variety of accessories for them and is the official Garrett metal digger dealer .
  • 2. Garrett : within this comparison of metal detectors it has turned out to be another of the most prominent brands. In fact, it is a world leader in the sale of this type of device and its users affirm that they stand out for the quality of their materials and for their ability to adapt to all types of terrain.
  • 3. Intey : This brand focuses on offering value-for-money metal detectors . They are recommended metal diggers for beginners and occasional users. Now we only have, based on everything we have told here, launch ourselves to buy the best possible metal detector taking into account our level and the use that we are going to give it.

Search For Metals And Other Hidden Treasures On The Beaches


The practice of searching for metals on beaches and in other environments has become a very entertaining hobby for many people. For others, on the other hand, it becomes a way of seeking a minimum subsistence.

In either case, we have two elements that must be properly analyzed. On the one hand, how to search for these metals and, on the other hand, whether or not we incur a punishable practice.

How to search for buried metals?

The best way to search for buried metals is to take advantage of metal detectors . In the market we can find a wide variety of models, from the most professional to the most modest for amateurs.

These metal detectors offer us endless options . For example, there are those who can search for treasures even under water; they have loudspeakers and headphones for underground metal detection; there are even some with extras like night vision or volume detector.

Some metal detectors even allow us to distinguish a classification between the search options. For example, they can allow us to search for gold, silver and copper , while the rest of the metals are discarded and are not included in the detection.

The hobby of metal hunting on the beach

This fondness for looking for metals on the beach has been promoted in recent years, as technological evolution has allowed better and better developments.

Today there are even applications for mobile devices that are linked to these detectors, to obtain more information and more precise data.

However, the fans may incur a penalty , if we do not comply with current legislation. The problem is that this legislation does not exist at the national level, but at the regional level. In this way, it may be prohibited in some Community, while in the one next to it it is not.

It is important to consult these permits, since the most serious penalties have reached up to 120,000 euros in some territories.

What we can tell you is in which places you cannot look for metals, unless you get an official permit to do so:

  • Archeology areas.
  • Sites with assets of cultural interest
  • Sites of historical interest.
  • Private fenced farms.
  • Public fenced farms.
  • Archaeological surveys.
  • Mineral prospecting.
  • Natural reserves.

Therefore, on the beach you can use a metal detector , as long as the Autonomous Community in which you are located allows it.

But not all metals you can keep. For example, if we find a treasure in a public property, 50% of its value will be paid by the State to the discoverer , but the object found will be kept by the Public Administrations, which will also be the legitimate owners.

In a private property this does not happen, because the treasure found can be acquired by the person who discovers it.

If what has been found has scientific or artistic interest , then the State itself is the one who makes an appraisal. 25% of its value will go to whoever discovers it, another 25% will go to the owner of the land and the State will acquire what has been found.

Reasons to plow the soil


Today, in this particular entry in Agromatic , we dedicate it to the soil. It is not for less since it is the livelihood of all plants, not counting those that are based on the pure hydroponic method .

We are going to comment on how doing some very simple tasks is capable of exponentially improving soil quality. A hard and tedious job, but one that reports magnificent results.

THE BENEFITS OF THE PLOW

With the plow of the suel or seek one thing: to improve soil conditions. This means that if for example we have a flooded soil, try not to accumulate water on the surface.

On the contrary, if we have a very dry soil, with high water filtration, we want it to retain water a little better and be assimilable by plants.

If we divided into segments those elements that significantly influence a soil and that, of course, affect plants, we could mention humidity, aeration, structure and also temperature.

Knowing what changes appear with the plowing of the soil with respect to these variables is important to know a little more about the land we cultivate.

Soil plow benefits


CONSERVATION OF MOISTURE IN THE SOIL

The humidity of a soil is influenced by its turning. It is something as we have told it before. If you have problems with water retention   ( slow drainage ), it will allow the water to drain better. And in the opposite case the same will happen.

A soil located in a desert climate will conserve the water in the subsoil much better after turning the earth.

IMPROVED AERATION AND OXYGENATION

Although we have already mentioned it in other articles, turning the ground allows you to increase the number of macropores in the ground.

These are responsible for storing gases (such as oxygen), which the roots of plants need so that problems do not appear.

A soft soil will allow the entry of air from the outside, which is also an entry of atmospheric nitrogen (which can be fixed by climatic effects, such as rain).

CONSERVATION OF SOIL STRUCTURE

A soil can have different textures, and that is what makes it classified as sandy, silty or clayey. It is a bit more complex than these three definitions, since there are mixtures between them, but basically it is that.

Depending on the plowing system that we use, we will get the land to change the size of its aggregates, being able to increase or reduce them.

This greatly influences both plant growth and seed germination .

If very large aggregates are left, greater than 5 mm, there would be an excessively large proportion of macropores, there is no water retention and the plant finds it difficult to absorb it.

A soil with very small aggregates , around 1 mm, produces an imbalance between macropores and micropores.

Indeed, due to the absence of the former, the water is not retained efficiently and we will also have problems with the development of the plants.

MAINTAINING TEMPERATURE

What does temperature have to do with the tillage or softness of a soil? Well, even if it doesn't seem like it, a lot.

The temperature of a soil is influenced by the environment and the climate where we are, as it seems logical.

However, by turning, the difference in temperature between night and day can be reduced. This is very important, because it allows a greater comfort of the roots and, of course, that is paid for with a greater development of the plant in general.

For this same reason it is advisable to leave the plow for another day if frosts are expected .

Air is a poor conductor so worse consequences are obtained if the air content is higher. A substitution of that air for water, a much better conductor, produces benefits and passively prevents frost damage.

Plowed soil microorganisms

 OK, WHAT ABOUT MICROORGANISMS?

Imagine that you were a microorganism (well, one day you were) in which you are given two options:

It grows in an environment without much oxygen, with little space, with unpleasant temperatures, and possibly waterlogged or excessively dry.
It grows in an environment with a balance between humidity and gases, with ease of movement, porous, without puddles, with a comfortable temperature and a granulated soil structure.
What option do you prefer? No need to answer.

What we mean is that although a priori we think that tillage produces mechanical damage to the soil, it uncovers beneficial worms and insects from the depths that later form part of the feeding of birds and other animals, the balance is corrected in a short time and the density increases exponentially in a short time.

Yes and no, we must clarify.

If your soil has a good structure , with good oxygen content, with normal drainage and in general, well, there is no need to till.

Why?

Because the microorganisms will be in charge of improving the soil even more and it would get worse with the plow.

You would modify the peaceful environment they have created and reduce the quality of it.

On the other hand, if your soil has poor drainage, is continually subjected to flooding and the soil structure is bad, the initial conditions for the development of microorganisms are bad or very bad.

Therefore, you have to act. Once they improve, you will not need to work frequently (in fact, it is not recommended).

ORGANIC MATTER IN A PLOWED SOIL

You have to think that with the turning, even if organic matter is not applied, its content also improves. How is this possible, if nothing has been contributed to the earth?

Because poor soil tends to create a surface layer of fertilizer compounds, including organic matter, at a depth where most herbaceous plants cannot access.

That is, the soil has a good percentage of organic matter , yes, but it is not balanced. You have a gold mine on the ground but you don't have the shovel and the pick to access it (well, today he gave us the similes).

When we plow the soil, if it is deep , we are removing deep layers with the superficial ones, so that all the mixture is distributed homogeneously.

Now all the mineral and organic content of the soil will be available to plants.

Without contributing anything, we have vastly improved soil fertility.

Not only that, since it is not about removing and disposing it to the crops. As we have a soft soil with greater aeration, all the nutrients and minerals that the organic matter houses are oxidized in greater volume and facilitate their absorption by the plants.

I WORK YES, BUT WITHOUT ABUSING

The balance of life allows us to use all the resources we want, up to a point. Any element considered as positive is so until it is abused, in such a way that once it reaches the peak of profit, damages begin to appear due to its abuse.

In fact, the current trend is conservation tillage . That is, plow only when necessary, not always annually, since in the long run, all the physical benefits that we obtained with the soil are lost.

The best thing is that we dedicate a future post to it, since it is also a long and widespread topic. You already know that you have our social networks and the subscription so you don't miss anything we post.

Tempero, the perfect soil for plowing


We have been talking for a few days about the benefits and drawbacks of tilling the soil. We discussed in an article the advantages of doing it and we also dedicate another article totally to the opposite, no tillage. For those who practice soil plowing, it is convenient to know what time is the ideal to do it. This is known as tempero. Let's see it.

TEMPERATE AND OPTIMAL SOIL CONDITION FOR TILLING

You just have to check or see a floor when plowing without enough moisture. Some very compact clods of earth come out. Then, after this previous plowing, a new pass (a complementary task) is necessary to break up these clods and leave the perfect soil for sowing.

Otherwise it would be when we plow with a soil that has accumulated enough moisture. Either because it has rained on the area or it has recently been watered. When plowing this soil, we find that, apart from the fact that the earth sticks to all the tillage tools, a "reinforced" mass is formed that is not beneficial at all when sowing.

LOOKING FOR THE EXACT MOMENT TO WORK, THE TEMPERO

Since neither of these two examples is ideal, we have to find the middle ground, which is not easy.

A farmer can wait a few days for the soil to "dry out" after it has rained. However, if the area is dry and it has been a long time since water has fallen from the sky, looking for the temperature is, so to speak, impossible.

Often it is necessary to resort to leaving the ground with clods after plowing and, later, to carry out a complementary work to break them up and that the soil is prepared for planting.

The temperature value is not usually established experimentally, rather intuitively. The experienced farmer is able to recognize a soil in tempera just by looking at it or by picking up a sample by hand.

WHAT IS TEMPERO BASED ON?

From a technical point of view, the word tempero is related to the forces of cohesion or plasticity that a soil has. When a soil is dry, that is, the humidity level is minimal, it cracks, it is quite fragile and it disintegrates easily. When we walk on it it is not able to deform without breaking.

As we have said, this soil will form large aggregates of soil (known as clods), often several kilograms in weight, which make any planting impossible. The seed would be lost among so many holes. It is the dry state .

In the  plastic state , the soil harbors enough moisture to deform without breaking into smaller aggregates. It is a very opportune state because, when plowing, large masses of land are not formed.

Finally, after a heavy rain or 'blanket watering', the soil is extremely moist. It is said that it is in a liquid state , it is nothing more than mud, a mass of land with a lot of water that when squeezed releases liquid that runs off between the hands. Obviously, the plow is unthinkable.

muddy ground without tempero

WHEN TO PLOW?
To get to classify it within a point of these three states , we could say that the temperature is an intermediate point between the dry state and the plastic. That is, the work allows large aggregates not to form nor does the soil have so much moisture as to make work difficult.

Dry soil without tempero

Very dry soil makes plowing extremely difficult

To add a more technical aspect to the matter, and not leave it to the expert eye of the farmer , said state of temperature is found when it has a humidity higher than the minimum in which the soil can deform and not break, and lower humidity than when we introduce a pointed object into the ground and dirt remains stuck to it.

Yes, the truth is that it is something difficult to explain ...

WHY DO THE WORK WITH TEMPERO?

Plain and simple, because it offers greater advantages than doing it at another time. When the ground is very dry, it offers great resistance to the advance of the implement, so the cost of the operation will increase considerably.

On the other hand, the result prevents direct sowing.

If the ground is very wet, when the implement and the tractor pass through the ground, it deforms to such an extent that the "work sole" is formed, the tire mark that usually gives away this tilling operation. If there is a lot of water on the ground, the machinery slips and makes it difficult to adhere, so the cost will also be higher.

The temperature, finally, is a recommendation for all those who will plow your soil, if the physical conditions of it are not good and you need to improve them. Remember that this operation has advantages and also disadvantages. Each case will have to be studied separately, as we have tried to do.

BASIC PRINCIPLES OF TILLING

"Soil preparation" is the physical manipulation that is applied with the intention of modifying those characteristics that affect the sprouting of the seeds and subsequent stages of growth of the crop. These characteristics determine the plant-soil-water-air relationships, which will affect the development of plants.

Soil characteristics that affect plant growth


a)  Soil structure.  It is the ordering of the soil particles, understood as such, not only the individual mechanical elements such as sand, silt and clay, but also the aggregates that have been formed into smaller fractions by mechanical action. The productivity of a soil depends to a large extent on its structure, therefore, the first objective of all primary tillage operations is to modify it to obtain a porosity that allows good gas and air circulation in the soil, facilitating growth. and root penetration.

b)  Soil aeration. It is important to decide the fineness of the tillage. Crops can only grow vigorously in an environment with good aeration, that is, where the concentration of carbon dioxide around their roots is low and that of oxygen is high. Therefore, the rates of transfer of carbon dioxide from the root zone to the atmosphere, as oxygen from the atmosphere to the root zone, are properties of the soil of fundamental importance for the crop. By increasing the volume of pores with the plow, the conditions of air movement in the soil are improved, causing a decrease in the content of carbon dioxide. However, excessive or poorly performed tillage destroy aggregation and increase soil density, reducing porosity,

In a vertical section of a soil, it is observed that at different depths there are layers of different appearance, called horizons and their set make up the soil profile.

  • Horizon A: Darker, better structure, good pore content.
  • Horizon B: Subsoil, accumulation of soluble substances and colloidal matters, with lower fertility than horizon A.
  • Horizon C: Original material, less affected by physical, chemical and biological agents. It is the least fertile horizon.

c)  Compaction.  Compaction is a problem that occurs in those soils whose structure is prone to destruction due to the effects of tillage and / or the action of water (rain or irrigation). Some degree of compaction can be beneficial, but when it is excessive, it can result in detrimental effects on soils and on the growth of cultivated plants. By reducing their porosity, it hinders the movement of roots, gases and water.

Soil compaction is the result of gravity, rain, and traffic. Of these, only the latter can be regulated by man and its action is "more severe" when organic matter is scarce, since the humus acts as a cement to give stability to the soil aggregates. As it is not possible to suspend the movement of agricultural equipment on the ground, methods must be used that tend to reduce the amount of work carried out on them. The effects of compaction increase with machinery traffic and even more so if the soil is loose at the time of starting work. This effect is also increased, when the soil has been worked with an intermediate moisture content (friable soil), a point at which it presents its maximum ease of loosening but also

The weight of the agricultural machinery and the working speed, together with the vibration of the drive unit, favor the general compaction of the soil, especially where practices that deteriorate its structure have been carried out. When a heavy tractor is used for tillage work, each "pass" causes two tracks in strips of approximately half a meter each. With subsequent work from the fourth pass, it is assumed that the ground is completely covered with tracks. The first pass of a tractor over freshly plowed soil has been shown to compact ten times more than a second or subsequent pass.

Therefore, it is advisable to "match" the traces of the subsequent passes so as not to generalize the damage and at the same time reduce the work to a minimum. It is recommended that the weight of the tractor and implements gravitate as little as possible on the ground, using wide tires with low pressures, especially when working on wet soils. The repeated use of the disc and / or moldboard plow at the same depth, compacts year after year the bottom of the furrow and forms a hard layer 3 to 4 centimeters thick, commonly known as "plow foot". This compaction limits root penetration, slows the movement of water and air in the soil profile and consequently causes drainage and erosion problems.

Another situation that requires special subsoil tillage treatment occurs in permanent grasslands subjected to direct grazing. The compaction produced by trampling animals is even more severe than that generated by machinery traffic, since the weight is distributed over a smaller surface in contact with the ground. This is particularly important in potato crops, which are generally used as a rotation head, after pasture.

The possibilities of compaction are greater in soils with a clay texture and in those with a low content of organic matter. Overworking that leaves the soil finely soft (especially with disc harrows) favors compaction and should therefore be avoided.

d)  Organic matter. Organic matter increases aggregation and improves the structure of soils. Continuous tillage practice has been shown to destroy aggregation and deteriorate its structure, simultaneously reducing its organic matter content. The incorporation of organic matter into the "topsoil" of the soil by plowing crop stubble and / or degraded natural or artificial pastures enhances the soil structure and reduces the negative effects of compaction. The same goes for the use of manure and liming. For organic matter to break down quickly, the stubble must be broken into small pieces and allowed to dry on the surface before being buried. It is also recommended, to speed up this process, add approximately 80 to 100 kg. nitrogen per hectare,

e) Soil moisture.  It is one of the factors that has the highest incidence in soil preparation work, both in plowing and scraping. Moisture makes the soil present more or less resistance to the penetration of the implements, it also gives it plasticity characteristics that allow it to adhere to the tillage implements, hindering their action. In very humid soils, traction is affected by increasing slippage and increasing power requirements, due to the great resistance it offers when moving the plow.

A soil with low moisture content is hard. As the humidity increases, it softens and breaks down easily. The friable consistency represents the optimal humidity condition to carry out the tillage of the same. This condition is recognized in practice by taking soil in your hand and making it easily disintegrate when pressed, without leaving any remains attached to it. Very wet soil forms a ball when "kneaded" and soils the hand with the wet clay that sticks. A too dry soil forms very hard clods that are very difficult to break up.

When the moisture content increases excessively, the floor becomes plastic, adhesive and very difficult to disintegrate, the action of the scrapers being useless. This is closely related to the type of soil. Sandy soils do not present these problems, but as the clay content increases, it is important to consider working the soil in friable conditions, as it is very difficult to manage. Clay soils require great dedication, because they quickly lose moisture in spring, being difficult to loosen.

From the above, it can be deduced that the soil's softness is closely linked to its moisture content and, therefore, the opportunity to carry out the work is more important than the number of times. A job done at the right time can have a definitive effect on obtaining the desired degree of fluffiness. However, it should not be forgotten that the moment when the soil is easier to compact, coincides with its friable condition, so it is advisable to avoid excessive traffic in order not to reach an excess of compaction.



OBJECTIVES OF SOIL PREPARATION


  • Release and remove the soil to create favorable conditions for the circulation of water and gases in the arable area of ​​the soil, at the same time facilitating the root development of the crop to be established.
  • Generate optimal soil loosening conditions for seed germination.
  • Control and destroy weeds that compete with the crop.
  • Increase the moisture retention capacity of the soil.
  • Eliminate those insects that constitute pests, their larvae, eggs and places of development.
  • Incorporate plant residues, fertilizers and lime promoting an increase in bacterial activity and an increase in organic matter.


There is no priority order of importance in the proposed objectives, given the enormous variety of soil, weed, pest and humidity problems present in the fields throughout the country.

OPTIMAL SEEDING BED

The seedbed corresponds to the entire soil profile that is altered by tillage work and its function is to create the ideal conditions for sowing, germination of the seed and subsequent development of the crop. In it, two zones are distinguished that obey different objectives and therefore require different characteristics: the seed zone and the root zone.

Optimal characteristics and conditions of the seed zone

The seed zone is the superficial one and must allow the increase in surface temperature and adequate humidity provided from the lower layers of the soil. Soil preparation generally begins in winter and when planting this area should present the following characteristics:

a) Depth : The land for a potato planting must have a surface layer of 8 cm. suitably soft, allowing aeration and accumulation of sufficient temperature for sprouting. Further down there should be a layer with higher moisture content, 15 to 20 cm. on which the seed tuber is deposited. These first centimeters of soil constitute the sprouting zone, therefore a good job of this part of the soil will ensure the best emergence of the plants.

b) Softness:  The degree of softness of the soil must be related to the size of the seed. When the clods are too large, good contact is not established with it, due to the air pockets that surround it and isolate it, they prevent the transfer of the humidity and temperature necessary for sprouting. The clods must not exceed 3 cm in diameter. The excessive fluffiness of the seed zone is not favorable either, since it destroys the structure facilitating the compaction produced by the water.

c)  It must be free of weeds , champas and live plant residues on the surface. Weeds compete with the crop for nutrients from the soil, water, and light.

d) Compaction:  It must be firm enough so that the planting machine can regulate the depth and thus allow a uniform location for the seed. In no case is it advisable for excessive compaction to occur in this area, which may limit root penetration and water and air circulation.

e) Humidity : It must have the necessary humidity to allow a good germination and development of the seedlings. Excessive tillage in the seed zone ventilates the soil and dries it quickly.

f) Temperature : In the potato-producing area this aspect is very important since the seed tuber to sprout requires temperatures above 9ºC in the soil. This happens from August onwards and especially if the paddocks have a northern exposure.

Characteristics and optimal conditions of the root zone It

corresponds to the deepest zone from where the extraction of nutrients, water and air that the plant needs for its growth takes place, and must meet the following characteristics:

  • a) It requires less fluffing than the seed zone.
  • b) It must have a granular structure that allows easy activity and root penetration.
  • c) It should not be compacted to allow better water retention and greater air movement in the soil.
  • d) It must be deep enough to allow the roots to have a wide area of ​​development (up to 25 to 30 cm).

This area must be removed by deep plowing, only this being enough to leave it in good condition. However, the plowing work should not exceed 28 to 30 cm. depth of soil, it is advisable to eliminate all the compactions present at the bottom of the arable soil (plow foot) that limit root development and the movement of water in it.

SOIL PREPARATION METHODS AND TYPES OF TILLAGE

a) Traditional tillage:

It is the soil preparation system that was used in a traditional way, and in some cases it is still carried out by small farmers. It is characterized by the repeated use of the moldboard plow, with which crosses and recruits are made that invert the soil, followed by a significant number of harrows with disc or nail harrows. In each plow pass a large amount of soil is moved, leaving the surface without vegetation cover.

The "cross" corresponds to the second plowing that is applied to a soil in the same season, this is carried out perpendicular to the first plowing. It is a practice that is identified with traditional farming and that does not always have a clear justification; However, when it is used it is mainly to solve the following situations:


Rectify a hole of irregular depth, and defective investment.
Deepening the "seed bed" when, due to the characteristics of the soil, it is not possible to achieve the desired depth with the first plow.
Loosen the soil that has been compacted by the rains. This case is common in the preparation of clayey soils (vegas).


Extract moist soil from the lower layers, burying the clods that have formed on the surface, as a way to facilitate loosening. If the previous points are analyzed, it is possible to verify that the cross can be eliminated in most cases, since most of them are the result of inappropriate soil management practices.

b) Conventional tillage: Soil  preparation system that uses moldboard or disc plows to give the working depth and invert the soil and a limited number of harrows with disc or nail harrows, vibro-cultivator, rotary cutters, rotators, etc. It differs from the traditional system by eliminating the work of crossing and recruza. In the same way, it moves a large amount of soil, and leaves the surface without vegetation cover.

c) Minimum tillage:  Faced with the large number of problems created by over-tilling, new methods of soil preparation are proposed, inspired by the principles of minimum tillage, which tends to reduce the traffic of machinery through the field.

To apply minimum tillage procedures, no special or sophisticated equipment is required. Common implements are used, arranged in tandem (one behind the other) and applied at the right time and in relation to the moisture content of the soil. Nor is more power required, since the tractors have enough reserve to cover the extra demand that means attaching an additional implement such as those mentioned.

The most frequent cases involve the execution of two or more tasks simultaneously, coupling several tillage implements to the tractor in tandem. Tractor, plow, subsurface roller and nail harrow coupled in line, often achieve a suitable seedbed in just one operation on some soils. Other examples could be: a subsurface roller or a nail harrow attached behind the plow, to prevent clod formation in medium to heavy soils; A nail harrow or a simple wooden harrow behind the disc harrow makes it possible to achieve a more finished soil loosening, while also sealing it on the surface to prevent moisture loss.

Currently the national agricultural machinery market offers a series of equipment that is based on this principle of minimum tillage, such as the combined harrow of nails and rollers; in addition to the strategic use of the vibrocultivator, rotary mills, rotators and chisels with stubble incorporators. The trend has been to replace the use of the moldboard and disk plows with the chisel plow, to give the depth of work, moving a small amount of soil from the profile and replacing the inversion of the soil with the chemical control of the vegetation or "Chemical fallow".

The best results with minimal tillage are achieved on medium textured soils. Heavy soils make it difficult for equipment to move because of its hardness, when the moisture content is low, and because of its adhesiveness, when it is too wet. These methods, however, can be applied on all arable soils, after eliminating natural obstacles such as stones and logs, in favorable humidity conditions. At present, tillage for potato cultivation has been reduced to such an extent that there are rotary mills that with just one pass allow the soil to be in suitable conditions for planting.



Another aspect to consider is the improvement of the planting opportunity, especially when it is prepared with a rotary cutter pass, which allows synchronizing the soil preparation with the planting. Only the surface that will be planted the next day will be prepared, thus becoming independent of the climatic conditions.
Despite the improvement of mechanization technology for tillage, the success of minimum tillage systems depends largely on the efficiency of the operator, quality of work and physical characteristics of the soil at the time of applying these methods.

d) Zero tillage : As in the case of cereals, the reduction of tillage in the potato crop has reached the extreme of eliminating it completely, thus creating a zero tillage system. In this case, the crop is established directly on the ground, covering the seed with a dense layer of stubble or cereal straw, which allows it to be protected from environmental factors such as light, wind and low temperatures, thus facilitating the development of the crop. Because planting and crop management are done manually, the system is limited to small areas.

Soil preparation times


Soil preparation must be planned well in advance, with the aim that sowing is not delayed by this concept. Most of the delays in planting are due to winter rains and excessive soil moisture, which prevents mechanized tillage from starting as early as desired, limiting the time available to prepare the soil, added to the fact that the decomposition of the waste buried by the plow is slow.

These considerations make it advisable to start the work of soil preparation for sowing in autumn (chopping and incorporation of the residues with plowing), then continue in winter or at the end of winter with superficial scrapes (control of the germination of weed seeds) and finish during the last month before sowing, deepening the break with a chisel plow (without inverting), leveling and conditioning the seed area. In general, the early potato planting date is July and the mid-season is August.

In the case of plain soils, soil preparation begins in October, once the humidity level has decreased. In the coastal sector, the sun and the prevailing south wind in spring dry the soil quickly, especially in the case of soils with a loamy-clay texture, with a great tendency to form clods. That is why the soil preparation must be done quickly, taking advantage of the friable soil condition. If clods do form, due to the action of the sun and the wind, it is best to plow with a moldboard or disc to bury them and "bring to the surface" moist soil in better condition to be broken up.

MACHINERY FOR PREPARING SOILS FOR SOWING

There is a wide variety of equipment for breaking, breaking up, leveling, compacting the soil, breaking clods, controlling weeds and shredding stubble residues from the previous crop. Most of these equipments are of different design, but they have been conceived to solve the same problem (disc plows and moldboards, vibro cultivator tandem harrow), or to act under specific soil conditions.
To determine the most suitable soil preparation method and correctly choose the equipment to use, it is necessary to clearly define the characteristics of the seedbed to be achieved, and to know the effects of the available tillage equipment.

Deep work equipment


Soil breaking equipment is classified according to its action: plows that invert the profile of the soil (discs and moldboards), plows that mix it (rotary) and plows that do not alter it (chisels and subsoilers).

a) Plows that invert the profile of the soil: These are those that are made with disc and mouldboard plows. Both teams invert the ground, but with different results, mainly due to their different design. Its operating characteristics cause differences in the quality of the plow, in relation to the inversion, softening and subsequent leveling of the ground.

The most important operating characteristic of disc and chute plows is their ability to bury manure, plant residues, degraded pastures and others. Both teams perform best in the presence of previously cut meadows to avoid "jamming" in the breaking units. The moldboard plow makes an excellent soil investment when operating on land that has not been recently plowed. When used on loose floors, you just move it sideways without inverting it. The opposite happens with the disc plow, it reverses a loose soil very well, causing unevenness of micro relief when used on meadow.

In soils with the presence of obstacles (stones, logs, roots, etc.) that are humid and with a clay texture, the disc plow performs better, since when turning, the breaking unit avoids obstacles and presents less resistance to the soil (the earth sticks less to the disc). Without the presence of these soil limitations, it is preferable to use the moldboard plow that protects the leveling, a factor that can be important when driving irrigation water.

b) Plows that mix the soil profile :

Rotary plows are breaking implements that require great dedication to use, because they subject the soil to excessive manipulation and can alter its structural characteristics. However, when these are used adapting the revolutions to the characteristics of the soil, they turn out to be highly efficient due to their speed and simplicity of use.

The blades attached to a rotor that rotates driven by the tractor shaft, cut pieces of soil and throw them against the plow housing to complete their loosening. The size of the pieces of soil depends on the speed of movement and the revolutions of the rotor. Most designs offer a wide range of rotor revolutions since they are equipped with a gearbox for that purpose. This implement can be used for the chopping of residues and for the destruction of clods, but it requires great power from the tractor's power take-off shaft and alters the structure of the soil, producing an exaggerated softness.

c) Plows that do not alter the soil profile : Chisel and subsoiler plows are tillage equipment that allows the soil to be disintegrated without altering its profile, cracking it by means of the action of one or more chisels attached to a rod or arm attached to a tool holder frame. The difference between both teams lies in the robustness of the structure, depth of work and number of chisels.

  • This type of work requires relatively dry soils for soil cracks or fractures to occur. Wet floors would be cut by the chisel like a knife, without producing the cracking effect of
  • drying. However, dry soil offers greater resistance to plowing, which translates into a high demand for power, which increases in direct proportion to the depth of work and the number of chisels on the implement.
  • The chisel plow is the right tool to destroy “plow foot” type compaction, improve water retention and protect the leveling and structure of the soil. Its main advantage is to deepen the seedbed without inverting the soil or causing unevenness in its surface, which indicates that it can be used first to condition the seed area and later to the desired depth. The separation between the chisels is determined by the length of the cracks or fracture lines produced, the important thing is that the cracks intersect enough to ensure a uniform treatment of the soil.

The subsoiler plow works under 30 cm of depth and is very useful to destroy natural compactions or those produced by the traffic of machinery or animals. It is also used in order to improve drainage, adding a pellet in the boot of this equipment to make underground galleries (mole plow). In this case, as an exception to the rule, work is done on damp soil, since it is not primarily of interest to loosen or crack the soil, but rather to manufacture underground galleries to remove excess water.

The use of the subsoiler on dry soil produces cracks of varying lengths depending on the implement used, humidity and soil texture. To determine the spacing distance between "subsoiler passes", the length of the cracks must be calculated using a trench and the spacing between "passes" should be arranged so that they intersect. The correct working depth of the subsoiler is also of vital importance, since if the boot works very deep and not in the compacted area to be cracked, the work is ineffective. In view of the intense traffic of machinery, typical of modern mechanized agriculture, it is recommended to subsoil the soils every 4 to 5 years.



Equipment for surface work


The basic function of surface work is to prepare the seed area through the use of various types of implements. Soil loosening, leveling, weed control, and the necessary compaction to ensure good crop establishment are its main objectives.

Modern agriculture has a wide range of equipment to fulfill this function, among which are disc harrows, nails, springs, scaffolding, vibro-cultivators, rotary cutters, rotary rakes, levelers, micro-relief levelers, rollers and others.

a) Disc harrow:  It is a very common tool in our environment and widely diffused throughout the mumps area. It is used mainly to loosen the soil and control weeds in the seed zone. There are two basic models that differ in the availability of discs and chassis bodies: offset offset disc harrows and tandem disc harrows.


The "efficiency" of the disc harrow depends on several factors:
• weight of the equipment
• size, concavity, cutting edge and angle of attack (lock) of the discs
• working speed
• soil moisture content.

This equipment works by cutting narrow strips of soil with lateral displacement of the same to cause its loosening. In addition, they cut the plant residues of the roof into pieces of variable size, depending on the dimensions of the equipment, soil condition and the locking of the harrow bodies. With regard to weed control, this equipment acts on the newly emerged seedlings, uprooting them so that the sun and the wind complete their destruction. It is also possible to use this equipment to chop the meadows as a pre-incorporation task.

Whatever the purpose of its use, it is desirable that the disc harrow acts at the maximum permissible speed and superficially to condition the seed area (tandem harrow). The off-set harrow is more efficient due to its design and weight, which is why it is recommended for use in heavy soils loosening and for the superficial chopping of stubble or vegetation cover. With a heavy off-set harrow properly locked acting on a light soil, a deep work similar to a plow can be carried out that only allows to loosen the soil without inverting it.

Special care must be taken to avoid the excessive use of this equipment, since its aggressiveness considerably affects the structure of the soil, and its cutting nature multiplies asexually reproducing weeds, such as chépica, blackberry and others. There is no justification to use a disc harrow to achieve the desired softness, when operating on loamy textured soils that are easily disintegrated, since there are other equipment with lower operating costs and greater efficiency and quality of work, such as combined harrows. of nails and rollers, vibro-cultivators and others.

b) Combined harrows :

They are highly effective equipment for the adaptation of the seed area. Except in very justified cases, this equipment displaces the disc harrow in its wide range of jobs, due to its cheaper cost and superior performance. Its action is based on the principle of minimum tillage that postulates the performance of several tasks in a single operation. Combination harrows are offered in versions with springs or vibro-activators and with rigid nails. The use of vibro-cultivators is recommended to carry out work a little deeper (10 cm.), In view of its greater aggressiveness, but both models satisfactorily fulfill the mission of conditioning the seed area.

The use of a combined harrow, like the plow, and like all the equipment that works in the seed zone, softening the soil and controlling weeds, is most effective when moving over 8 km / hour, which allows a large capacity of work. Another combination harrow design recently incorporated into national agriculture is the shaft driven rotary nail harrow that takes power from the tractor.

There are a wide variety of designs of the breaking unit, highlighting the horizontal axis rotor system with nails or hoes and the vertical rotating and oscillating nails. The mechanical action of great force that is exerted on the soil, gives this equipment special conditions for the loosening of clods and chopping of meadows, especially under extreme conditions (dry clay soils and dense and hard meadows). Although it is the best tool available to chop grass meadows prior to their incorporation with soil preparation work, it is not convenient to generalize its use, since it consumes a lot of motor energy and puts a special effort on the tractor system. of transmission.

It is not recommended to use a rotary cutter to loosen light-textured soils that disintegrate easily or to control newly emerging seed-breeding weeds, since a combination harrow of fixed nails or springs and rollers can do this at low cost and very quickly, without using the axle, it takes power from the tractor.

c) Spring, nail and roller harrows : They are also very useful to fine-tune the finish of the seed bed. The first two are preferably used to control germinating weeds in their early stages of development. Like combination harrows, it is desirable to operate at high speeds to obtain good soil loosening and weed eradication. The rollers, whether smooth or corrugated, surface or subsurface action, seek to complete the loosening of the soil and compact the seedbed to give it the firmness it needs to support the seeder unit.

The machinery market offers a wide variety of equipment for surface shavings, both motor and animal traction that allow the user to select the tool according to its energy availability. As for the types of rollers most used in our environment, they range from wooden ones, metal ones that can be filled with water and those with a combined action of a spray roller with a double run of corrugated rollers and a spring harrow between them, considered an excellent team to destroy clods and finish the refinement of the seed area.

d) Micro-relief levelers or rakes: Micro-relief levelers are generally used to leave the soil in conditions that allow precision planting, such as beets. In the case of potato sowing, rails or rakes can be used to fine-tune the seed bed at the end of soil preparation. They are generally used after planting to clear the seed furrow left by the planting machine or to compact and smooth the soil surface when planting is done manually.

SPECIFIC PROBLEMS IN SOIL PREPARATION

In potato production there are no relevant problems in soil preparation, which hinder or affect the establishment of the crop, although the preparation work has been carried out with simple machinery or animal traction. The problems generally appear at the time of mechanized harvest, in which the potato is bagged; and it is related to the formation and presence of clods, which behave the same as a tuber, so when carrying out a mechanized harvest with bagging, a large part of them pass into the sack, which later arrive at the winery.

Clay soils with a tendency to lump formation

a) Factors that favor the formation of clods:  The formation of clods occurs due to the loss of soil moisture and depends on the texture of the soil and the prevailing climatic conditions (wind). The higher the clay content, the more difficult it is to work the soil and therefore prepare a fluffy seed bed.
Clods do not exist naturally in the soil, being the result of poor work done by man. The plows carried out on clayey soils that are too humid and inopportune scrapes accelerate the drying process of the soil, increasing the surface exposed to the wind and sun, facilitating the formation of clods.

Farmers often do not start scraping to loosen the soil until they have finished all the plowing they want to do in the season. This means that the plowed soil is exposed to the wind and the sun for a long period, giving the opportunity for it to dry out more in the part exposed to the air. The work of scraping with discs on this soil condition separates the dry blocks from the wet ones, giving rise to clods, the size of which depends on the clay content of the soil and the leveling achieved by plowing. Moldboard plows allow for a more orderly inversion of the terrain, and are less prone to clod formation.

The presence of hard and dry clods forces the farmer to carry out an excessive number of scrapes with the intention of loosening them, objectives that are not always achieved, increasing tillage costs and accelerating the loss of soil moisture.

b) Methods to avoid the formation of clods:
  • I) Plow and track at the right time in relation to the percentage of soil moisture using subsurface rollers behind the plow to level and offer less contact surface to the wind.
  • II) When the soil is friable, carry out a single harrow to achieve the desired softness. It is recommended to use combination nail harrows and sub-surface rollers immediately after plowing.
  • III) Use wooden rakes and / or rollers attached behind a disc harrow to "iron" the ground and prevent moisture loss.

The opportunity of the scrapes in relation to the moisture content of the soil is essential to avoid the formation of clods.

c) Methods to destroy clods on dry soils in the entire topsoil.
  • I) Irrigation: Return the moisture lost to the clod to bring it to a friable level that is easy to fluff through artificial irrigation. This method, however, delays cultivation and increases the number of soil preparation tasks, since it is inevitable to re-plow the soil to loosen it and destroy the compaction produced by irrigation.
  • II) To soften the dry clod by means of the impact of motor-powered equipment, for example, the rototiller or rotary plows.
  • III) Pressure exerted on the dry clods by a leveling equipment or roller. The latter case has given excellent results using the leveler - chisel plow combination on very clay dry soils. Also in the above cases, it is appropriate to use a chisel plow after watering or after the rototiller, in order to deepen and loosen the soil.

d) Methods to destroy clods on dry soils in the superficial layer (8-10 cm) and humid in the base.
  • I) If there is no humidity in the first centimeters of the soil, there is sufficient humidity in the lower layers of the soil, it can be rolled to introduce the clods in the humid zone and then trace it, when the clods have
  • been impregnated with enough moisture to recover friable condition.
  • II) It is also possible to resort to "crossing" to bring moist soil to the surface and be able to soften it later, by means of superficial scrapes.
  • In summary, it is important to carry out the scraping work in a timely manner, which will subsequently soften the soil based on a high number of tasks, since this implies a misuse of equipment and high operating costs.

Soils with a high degree of infestation of seed-reproducing weeds
a) Contamination of the soil with weed seeds : It is practically impossible to eliminate the problem of seed-reproducing weeds by applying mechanical tillage methods, due to the permanent infestation of new weed seeds brought by the wind, irrigation water and animals. Soil preparation is only intended to retard weed development to give a growth advantage to the crop to be established.
  • The weeds that seed in the abandoned stubble and those transported by irrigation water are the only ones possible to control by man, since they are deposited on the surface of the soil and are buried with the plowshares and distributed uniformly throughout the profile arable.
  • Despite the entire profile of the seedbed being contaminated, only the seeds that are in the first few centimeters can germinate and the rest waits stratified for their opportunity to germinate. The seed can retain its germination power for several seasons as long as the conditions are not in place for it to be activated.

b) Measures to control weed contamination
  • I) Use adequate cultural rotations in order to create unfavorable environments for the development of weeds.
  • II) Process, with clearing equipment, the stubble immediately after the harvest is finished and repeat the operation as many times as necessary, to prevent the weeds from seeding.

c) Opportunity to control germinating weeds : The weed seeds present on the surface are activated by the humidity and temperature of the soil, a phenomenon that occurs when this area is prepared for cultivation. Once the germination of the weeds is activated, the process is irreversible, that is, from that moment the situation can be controllable.
  • Being easier to control the weed when it is germinated or just emerged; It is advisable to do a leveling work 10 days before sowing to provoke the germination of the weed seeds, with the compaction and loosening effect of this equipment.
  • Soil moisture also has a great influence on the effectiveness of weed control by harrowing. If the soil is very wet or it rains after raking, the action is canceled, since the roots of the uprooted weeds return to their initial position. If the soil is dry, there is no point in scraping since the seeds have not yet been activated.

d) Weed control methods with harrowing tasks : The weed control carried out by the different types of harrows mentioned above, consists of uprooting the seedlings and leaving their bare roots exposed to the action of the sun and the wind for their definitive destruction. It is a mistake to think that the mission of these teams is to crush or chop the weeds, destroying them with blows. From the foregoing, the importance of tracking growth and humidity at the right time, to obtain a successful control, follows.
  • Each movement of the soil removes new weed seeds to the surface layers, leaving them in conditions to germinate, so it is advisable to carry out the soil preparation work from greater to less depth, in relation to the control of germinating weeds. It is not intended to carry out deep work after surface scrapes that have the mission of controlling weed seeds germinated on the surface, since this work will deposit new weed seeds brought from lower layers, canceling the action of the previous control.

It is advisable to plow only once and do the job well, to avoid a cross that would have the effect of nullifying the control of germinating weeds carried out by the scrapers. After this plowing and when soil moisture is advisable, increasingly superficial scrapers should be administered, preferably using combined harrows of nails and springs, of great efficiency and performance. From the point of view of germinating weed control, one scrape after another should not be applied, since it is necessary to allow time for the weed seeds that were in a favorable position to germinate.

Soils with meadows

It is common to find seed beds with a large amount of residues from the paste on their surface, which makes the operation of the seeder machine difficult. This problem is caused by directly breaking the meadow with a disc plow and distributing residues or grass champas throughout the profile. From that moment the problem of the champas is out of control, since a new plow to bury the residues of the surface, can remove those that are already buried.
Despite the number of scrapes applied after plowing, the champas will remain in the profile for two main reasons:

to. The harrow needs a hard surface to hit the grass against in order to cut it into small pieces and the loose soil, removed by the plow, will act as a shock absorber preventing this objective from being achieved.
b. The decomposition of organic matter is very slow in the south, where this problem is typical, such that the waste persists for several months without decomposing.
In the case of natural grasslands, it is convenient to crush the weeds superficially with a disc harrow, rototiller, or rotary cutters, expose them to the action of the sun and wind for a few days, and then incorporate them with a deep plowing work. It is recommended to do these tasks at the end of summer. Plowing can be replaced by the use of chemical fallow.

The scraping should be practiced superficially in the first 8 cm of the ground, so as to always have a hard surface against which to hit, to get a better cut of the champa. In the case of using a tandem disc harrow, which is more effective than the offset harrow for this task, it should be adjusted with a low angle of attack (lock) and proceed to carry out the work 2 to 3 times, passing in a crossed direction. In the same way, it can be replaced by a vibro cultivator that can be more efficient and faster. The harrow passes must be spaced apart to allow the action of the wind and sun on the debris.

For the subsequent incorporation of the chopped material, it is preferable to use a disc plow, since it inverts the soil very well when it is loose and without the mooring of the root mass of the pasture.

Soils with vegetative reproduction weeds

To prepare soils that have a vegetation cover with vegetative reproduction weeds such as chépica, onion grass, yarrow, among others; One must be very careful in the selection of tillage implements, since the rotary discs and harrows chop the roots, spreading weeds that multiply very easily. In these cases, the use of tools such as the mouldboard plow and the nail and spring harrow to uproot the chépica is recommended. Chemical fallow with the use of Glyphosate (Roundup, Rango) is a very good alternative in this situation since it efficiently controls grass weeds. When there are more complicated broadleaf weeds, Glyphosate can be mixed with 2,4-D (amine or ester), Ally, Ajax, Aliado, Tordon 24-K, MCPA.

Soils with compaction type «plow foot»

The compaction produced by the repetitive action of a plow that always works at the same depth, creates important problems for crops. It is advisable to perform subsoiling work at least once every 5 years to soils subjected to intense machinery work and / or with animals in direct grazing. In the same way, the permanent passage of the chisel plow should largely solve this problem, provided that the plowing is carried out on dry ground and at the speed recommended by its manufacturer. The method takes advantage of the characteristic of the chisel plow that does not alter the soil profile, to reverse the traditional process of plowing first and then tracking.

The residue is chopped, buried and the seed area is traced, and then chiselled in depth, taking advantage of the fact that the first centimeters are loose and offer less resistance to the implement. Another interesting aspect proposed in this method is the replacement of the disc harrow by the leveling harrow, which does an excellent job of tuning.

On soils with stubble on the surface

Chopping up the residue before plowing is always a good method because it uses the resource in favor of the soil and facilitates the investment of the plow. Not processing the residues complicates the operation of the plow and remains of the stubble remain on the surface.

ORGANIZATION OF MECHANIZED TILLAGE WORKS

One of the typical problems that farmers who want to start preparing a planting bed must face is the choice of the direction or direction of work. Several factors should be considered to solve this problem, among which are: the conservation and protection of the soil, the work capacity or performance of the equipment and the quality of the work carried out.

Factors determining the direction of work

a) Soil conservation and work direction:  When the soil is removed by the tillage implements, it can eventually be washed away by rain or irrigation water, and lost through erosion. If the plowing with discs or moldboards or other work that leaves grooves in the direction of work, is carried out on soils with a steep slope, the orientation of the contour lines or the direction of the least slope should be chosen. In this way it is avoided that the rainwater descends at high speed through the furrows, dragging the soil and forming cracks that are almost impossible to recover. In addition, the tractor or draft animals have greater difficulty working against the slope (uphill).

b) Direction of work and performance of teams:  The work capacity of a team, or the time it takes for it to cover a given area, is measured in hours per hectare or hectares per hour. The working capacity depends on the speed, working width and time lost in non-productive actions, such as turning on the paddock heads with the implement raised.

This last factor, which is also called field efficiency, affects the final performance of the equipment, since the width and working speed must be kept fixed depending on the power of the tractor. From the point of view of work capacity, to avoid lost time due to turns with the implement raised, the tasks should be oriented in the direction of the greater length of the paddock. Another technique that avoids excessive loss of time at the ends of the paddock is to leave wide heads to allow the tractor to turn without resorting to gear changes or use of the clutch, and to prevent unnecessary deterioration of the transmission system. They can also be left wide heads and sides, of equal measure, in order to later close the work by circulating around the worked ground.

c) Direction of work and quality of work

Plowing:  When this task is carried out with a chisel plow, which does not produce unevenness in the ground due to its symmetrical condition, its quality is not affected mainly by the direction of the work. The same does not happen with the disc and mouldboard plow that require a method to avoid unevenness on the surface. The cross that corresponds to a second plow to rectify or increase the depth of the seedbed, it is advisable to apply it in a direction perpendicular to the first one, in order to achieve a better penetration of the plow, provided that a raking to improve the surface leveling of the terrain

The subsoiler plow should preferably be used in the "direction" of the greatest length of land to improve performance. However, it is advisable to use it in the direction of the slope when its function is to improve the drainage of a flat floor.

Scraping:  As its function is to loosen and even the soil, it is convenient to apply it in a 45 degree direction to the plowing line; in this way, the tractor wheels are prevented from falling simultaneously into the traversed furrows, which causes sudden movements that impair operator comfort and machine maintenance. Furthermore, a better leveling effect is achieved than when operating in any other working direction. The combined harrows and rollers can be used in any direction since this does not influence the quality of your work, being more important in these cases, the performance of the equipment and the speed of movement.

Leveling:  Leveling a previously plowed and traced soil generally requires 2 to 3 passes with the equipment to achieve an acceptable correction of the micro relief.

Tillage reduction

Potato cultivation has been characterized by the excessive use of soil preparation work, mainly with traditional systems that implied the use of a moldboard or disk plow and the practice of crossing and recruiting.

Trials carried out in the 70s and 80s by INIA Carillanca and the Austral University of Chile indicated that it was feasible to reduce the number of soil preparation tasks without affecting crop yields. At present, such a reduction has been reached, that with only one work of a rotary cutter with 35 cm tines, it allows the soil to be left in conditions to carry out the planting of potatoes.
