Balanced and timely supply of plants with micronutrients is one of the important points in the complex of elements of precision farming and obtaining high quality and large yields, for the formation of which microfertilizers are used.
They consist of individual chemical elements and their various combinations necessary for normal plant growth, nutrition and health. Such fertilizers are well absorbed by any crops, with each trace element acting directly on all metabolic processes, their growth and nutrition. The peculiarity of microfertilizers is that each element is responsible only for a specific function and because of the unique composition cannot be replaced by another component. There are several types of microfertilizers. Let us consider in detail one of them – humic. These are natural organochelates obtained by treating peat or lignite with alkali at high temperatures. Leaf fertilizers with humic acids are presented both in mono-variants of basic trace elements and complex compounds. Humic preparations with trace elements in chelated form enrich the soil, quickly restoring the metabolic processes of the crop and providing an increased supply of useful substances.
Application of microfertilizers in agricultural production
Application programs and dosage of complex microfertilizers are built on the basis of reliable information about the content and amount of trace elements in cultivated soil and crops. Depending on the biological characteristics of the crop and soil and climatic conditions, the dosage and phases of mono-fertilizer application vary:
- Winter rape – during the growing season, attention should be paid to the application of 150 g/ha of boron and 50 g/ha of manganese in the fall during the tillering phase and in spring in two stages: at the beginning of the growing season and at the end of budding.
- Corn – reduces the intensity of development and growth with a lack of phosphorus, zinc. Leaf feeding is recommended at a dose of 100-150 g/ha in the phase of the formation of 6 leaves on the shoots.
- Winter grain crops – need manganese and copper. A mixture of these micronutrients is applied at a dosage of 50 g/ha at the beginning of the plants’ emergence into the tube.
- Sugar beet – sensitive to boron, which should be introduced in two phases: the first time at the formation of 10 leaves on the plant and the second time – 1 month after the first fertilization. The dosage ranges from 200 to 300 g/ha depending on soil chemistry.
- Flax fiber – zinc and boron are significant for this plant. Root treatments are carried out at a rate of 50 to 100 g / ha of boron and 70 to 150 g / ha of zinc in the phase of seedlings height of no more than 4 cm and no more than 6 true leaves.
- Potatoes – the greatest demand for this crop in boron, which increases the yield, protective properties of tubers and their storability. For fertilizing, 100-50 g/ha during the budding period is enough.
- Legume grasses – seed plots require fertilization with molybdenum fertilizer and boron at a dose of 50 g/ha at the stage of crop budding.
Peculiarities of application and results. Advantages of the organochelate form
Application of organic fertilizers in mono-variant or micro-complex should be carried out taking into account the group of provision of soil with trace elements and climatic conditions. For groups I and II, as well as during the dry spell in the phase of the growing season, it is recommended to apply the maximum doses of fertilizers. In this case, foliar feeding at any period can be carried out in conjunction with the use of fungicides and insecticides. For foliar feeding, it is necessary to prepare solutions just before use. Microfertilizer application in the solution is carried out with deflator or slot sprayers.
When choosing the time of application of fertilizers, not only consider the weather conditions, but also the biological characteristics of the crop, which, depending on the species can absorb micronutrients from 1 to 2 days. It is best to feed during cloudy weather or in the afternoon. The result of taking into account all conditions of fertilizer application will increase yield growth and quality by at least 10%, due to the pronounced benefits of organochelate form:
- rapid absorption of components;
- absence of toxicity;
- effectiveness in all soil acidity ranges;
- elimination of precipitation of trace elements in interaction with agrochemicals;
- increasing the protective properties of plants, which become more resistant to diseases, drought, temperature fluctuations.
Scientific and economic substantiation of the need for microfertilizers
The results of research and data study, prove the feasibility and cost-effectiveness of the use of microfertilizers in agriculture. Tests of batches of complex fertilizers, mono fertilizers showed that the addition of boron in leached soil, allowed to get an additional increase in yield, which in sugar beet about 4 t / ha, cabbage – 0.29 t / ha and pea 0.37 t / ha. Molybdenum application provided an additional harvest of 0.6 t/ha of legumes. The use of copper-enriched fertilizer on peat-bog soils increased the yield of vegetables by 20% and barley by 18%.
The results of application of organochelate microfertilizers produced by ” Zoloto Poley” are collected in the brochure “Results of application. Issue 3”, which can be viewed on the home page, as well as in the “Results” section.
