What is ferantization and which fertilizers use for it?

Farmers and gardeners can be very interesting what it is – Fertigation. In our article we will look at the ferration system at drip watering, we will give an overview of the equipment and norms of the insecticide consumption. Separate theme are used fertilizers.

What it is?

Already in deep ancient times, Pahary, gardeners and gardeners found out that fertilizer should be made to the ground – then its productivity is maintained at a very high level. Many centuries and even the Millennium The main experiments went with various chemical compositions of fertilizers. But only recently revised the approach to their bookmark – from solid additives, more and more began to move to liquid. So the fertigation appeared The original method of introducing nutrient components into the soil, which allows you to count on high yields and is attractive from an economic point of view. For the first time, such decisions began to be used in the 1970s in Israel.

There were introduced a drip irrigation system of desert lands. And it was quite logical that the fertilizers and other necessary substances can also be added exclusively as irrigation. This technology quickly picked up in other states where fertigation apply on many millions hectares. The area covered by it annually increases. All organic and mineral components are mixed in advance, so their delivery to the root system passes as quickly and efficiently as possible.

Specific norms of consumption of insecticides depend primarily from the drug used. So, the popular “actor” consumes 0.4 kg per 1 hectare with a height of stems up to 1 m. If it is more than this mark, the costs increase twice. “Exploshot of Energy” use 3 l per 1 hectare.

You need to be guided primarily by the instructions of the manufacturers, and with any doubt – to seek advice on experienced agronomas.

When necessary?

Fortigation is used mainly in industrial agriculture. There, it becomes increasingly developing into aircraft – the art of growing plants without soil. However, an increasing number of gardeners and gardeners are also attached to fertigation technologies. The advantage of this technique is that liquid fertilizer is much easier to distribute homogeneously than a solid substance. This circumstance is especially important when the content of “capricious” crops, which suffer from both insufficient and excessive subcording.

The absorption of nutrients will occur by 100%. Therefore, bookmarks can be less common and less, reducing the laboriousness of the work and eliminating an excessive load on the natural environment. Unlike the usual fertilization, you can not adapt to weather parameters. The cost of feeding is lower, since the prominent part of the direct efforts of workers is replaced by the contribution of automation. It becomes possible to add fertilizers in the second part of the growing season when mechanically feeding plants is very hard.

Drip feeding with useful substances very much helps on areas with uneven relief. The situation is excluded when the main part of the substance is collected in the lowland, and the tops of the relief are not allowed to. Since even solid compositions have to dissolve, the difference between them and liquid feeders in the convenience of use disappears. Irregular losses of nutrients are minimized. The method is equally well manifested in an open and closed soil.

However, fertigation has weaknesses:

  • You have to purchase, install equipment;
  • The calculation of dosages is very complicated, and only prepared professionals can make it clearly;
  • there is a possibility of clogging of the irrigation system with insoluble remnants;
  • Not all fertilizers can be applied in this way.

Necessary equipment

With drip watering and fertigation requires quite a variety of equipment. Injectors play an important role. They injected fluids into a stream under pressure. The outer body is made of polypropylene or polyvinyl chloride. Using injectors, you can perfectly mix the fluid using the pressure difference.

When liquid falls into the injector, it pushes into the pumping chamber, where it starts to move faster. In this case, the pressure drops, and the new portion of the substance is drawn. Modern injectors are designed by calculating the minimum pressure difference between the input and output parts. There is such a technique inexpensively and almost always costs without external sources of energy; Serve it uncomfortable. On the leading plantations, the ferantization is carried out using dosing pumps that ensure the most accurate distribution of fluid. In particular, such a technique supplies an Israeli concern “Tefen”. Produced by the dispenser Mixrite does not need power. Drive force takes from the pressure of the water pipeline. Pressure consumption is minimized. The device itself is unpretentious and also does not require complex maintenance, it is widely and successfully used in different parts of the world.

For fermenting often use more injector dispenser “Venturi”. But the feeding substances themselves are always in a helpful container. It is a tight closed tank. There are cranes in the inlet and on the bulk contour.

Fluid flow due to a small pressure drop. The injection unit smoothes the fluctuations in the concentration of the solution, and at the main irrigation system there is already a homogeneous mixture.

Used fertilizers

Above mentioned above, the limited variety of applied compositions. And the main reason for this is that only liquid and water soluble drugs can be mortgaged. Among the latter allocate:

  • “Crystal”;
  • “Terraflex”;
  • “NOVALON”;
  • Combined “Kemir”;
  • “Ferctare”;
  • “Universol”;
  • potassium monophosphate;
  • urea.

Under the ban on rare complex fertilizers. Attempt to make them turns around often the full way out of the irrigation system. It is undesirable to use low-soluble substances, such as nitroammofosk. Before using the unknown feeding, you need to prepare it and test it on the irrigation line samples. It is impossible to ever exclude even the fact that water will unpredictably respond to new chemicals.

Fertilizers start adding about the 20th minute of drip irrigation. By this time, the head in his line is stabilized. Celebration session is at least 1 hour. For the same time you need to wash off the line with clean running water.

It is extremely undesirable to introduce more than 1.2 kg of fertilizers per 1000 liters of water – it is better to limit 1 kg at all, and the exact dosage is made using agronomes individually.

Through the FERTIGATION system, you can add all the batteries required by plants. But in most cases are limited to phosphorus, nitrogen and potassium. Calcium and magnesium additives are less common. Fortigation by trace elements is recommended only for those rare cases when it is impossible to do with extraordinary feeding. When selecting specific fertilizers, attention must be paid:

  • on the actual needs of cultures;
  • phases of their growth and development;
  • interaction between ions;
  • the specificity of the soil;
  • Water characteristics;
  • cost and prevalence of fertilizers;
  • compatibility of feeding.

For convenience, the life cycle of all plants is divided into 3 main periods: from the formation of shoots or disembarking in the finished form before flowering, from the formation of flowers to the folding of fruits; Stroke and Completion of Fruit. In each of these periods, fertigation solves specific tasks. As with normal feeding, the bookmarks of many fertilizers should be avoided immediately before frolification and during its. This may lead to dangerous compounds. At each stage, they still support the optimal proportion between the nutritional elements and take into account the interaction of their specific forms.

On alkaline lands, nitrogen fertilizers and carbamide. Ammonium can also be used without special limitations, like potash micro, macrobractions in chelated form. The only exception is FE2+. In acidic lands it is impractical to use physiologically acidic nitrogen mixtures, as well as phosphoric acid.

When choosing between equal type of action, the compositions take into account the temperature of the Earth.
