Use of CZR and microfertilizers in corn cultivation


Among the crops of modern agriculture  corn  occupies one of the leading positions. The success of the breeders and the perfect cultivation technology can bring the yield of this crop to a fantastic yet very recent 10-15 t / ha in the weighbridge. This factor is one of the main factors influencing the rapid growth of sown areas of culture in Ukraine. In addition, corn is one of the best insurance crops sown in the event of freezing of winter crops.
Of course, in order to obtain a high corn grain yield, it is necessary to ensure sufficient mineral nutrition of plants and reliable protection against weeds, pests and diseases. Among the products that are marketed by the company AHK Group, we offer ground  activated activated carbon herbaceous Actechlor (900 g / l Acetochlor) , Kieler insecticide  55% (Chlorpyrifos 500 g / l + cypermethrin 50 g / l) , as well as microfertilizer line for optimization of mineral nutrition of plants , overcoming the stress of plants under the influence of adverse weather conditions, the manifestation of phytotoxicity of herbicides and the like.
Acetate primer herbicide is intended for the destruction of annual cereal and dicotyledonous storks. Effective against many storm-eaters, in particular, one-year two-seeded: Galinsoaga, various species of bitterflies, common gracias, common stomach, giant Canadian, middle starter, theophyte canal, white loboda, lutegah, black currant, portugal gardens, chamomile, rhubarb, gherkin, ambrasia polynolist . Effective against perennial weeds: thistle pink (seedlings), rubbery, or millet, butterflies (seedlings) and cereals: mice (seedling) blue, mouse green, millet chicken, flask blood-red, ovsygu, geranium.
For the effective action of the herbicide, the following recommendations for use should be guided:

  • the soil must be well prepared (free of large lumps that increase the absorption area and, accordingly, reduce the effectiveness of the herbicide);
  • the introduction of a herbicide is carried out on the surface of the soil;
  • Aztec acts on weeds only in the phase of seedlings;
  • the effectiveness of Aztec depends directly on the presence of moisture in the soil: the optimal conditions are formed, if after the introduction of the rain or watering (10 - 20 mm). If the soil is sufficiently moist, then you can not make a profit if the soil is overdue; the herbicide must be made by mechanical means (light harrows);
  • the terms of application depend on the conditions in a particular field: from 3 to 14 days before the sowing with compulsory earnings. However, keep in mind that during the sowing the integrity of the protective screen will be broken. The best introduction period - right after the sowing to the emergence of stairs with the earnings of light harrows. Without acreage Aztec is introduced in areas with a large number of plant remains and high probability of rain after spraying;
  • recommended flow rate of the working fluid in the range 200 - 400 l / ha. Aztec can be used in tank mixes with other CZRs and fertilizers in the absence of precipitation, which needs to be checked before use.

Insecticide Kieler 55% (Chlorpyrifos 500 g / l + cypermethrin 50 g / l) is recommended to be used in the fight against stem corn butterfly and cotton scoop. Insecticide is used during the mass fly of butterflies. The consumption rate is 0.6 - 0.8 l / ha.
Corn is demanding to the conditions of mineral nutrition, which is connected, first of all, with the long vegetative period and the property of the plant to absorb nutrients until the end of ripening of the grain. On the formation of a grain yield of 5-6 t / ha, corn carries 130-150 kg of nitrogen, 50-60 kg of phosphorus and 120-130 kg of potassium on average.
An important place in the mineral nutrition of corn plants are microelements. During the growing season, plants assimilate up to 800 g / ha of manganese, 350-400 g / ha of zinc, 70 g / ha of boron, 50-60 g / ha of copper. Traditionally corn is considered as an indicator of the content of trace elements in the soil. Especially sensitive maize is the lack of zinc (Zn), manganese (Mn), copper (Cu) and boron (B), which affects the growth and development of corn plants and leads to a decrease in the productivity of the crop.
Zinc is involved in the synthesis of chlorophyll and vitamins, affects the processes of growth and development, increases resistance to adverse conditions, including frost. Due to a significant shortage of zinc, plants may not be tied to the beginnings. The sign of a lack of zinc is intermixed chlorosis, which first appears on younger leaves.
Bohr positively affects the processes of fertilization and the formation of grain, the hydrocarbon metabolism and the processes of breathing. Lack of boron causes inhibition of plant growth.
Copper affects the increase in the content of protein and sugar in grain, contributes to increased yields, resistance to disease. Lack of copper can be manifested for the introduction of high nitrogen and phosphorus levels during arid and warm weather.
Given that in most cases the soil reserves of available microelements are not sufficient to provide them with the required amount of plants, there is a need for additional inclusion in critical growth and development prototypes. The most effective way of introducing micronutrients is the foliar application of micronutrients in the form of chelates.
During this period, we offer endocrine fertilization with micronutrients  Ecoline ZincEcoline Universal Start  and  Ecoline Magnesium  which are complex fertilizer microbes.
Recommended doses for foliar feeding are in the range of 1-3 l / ha.
Ecoline Zinc  - Microfertilizer is intended to eliminate zinc deficiency for corn plants in the initial stages of development. According to the recommendations of scientific institutions, the trace element of zinc should be given to plants in the phase of 2 - 4 pairs of these leaves. This period in the development of corn plants is critical.
Ecoline Magnesium is  intended for foliar application of crops with periods of intense growth and is a unique complex of trace elements in chelate form. Recommended for use in crops that are susceptible to deficiency of magnesium and iron, as well as in the cultivation of other crops in the lungs, with particle size distribution of soils, slopes more than 5 degrees, during a hot period, when plants may be deficient in iron and magnesium, even with sufficient content of these elements nutrition in the soil. The dose for foliar nutrition is 1 - 2.5 l / ha.
Ecoline Universal Growth  and  Ecoline Corn are  recommended for foliar application of crops after forming on the plant 8 pairs of leaves.
The use of microfertilizers contributes to a significant increase in crop yields, improvement of the quality, increase of the efficiency of application of mineral fertilizers and pesticides. Especially recommended for preventing and overcoming stress in plants. Recommended rate for corn is 1.5-3.0 l / ha.
Depending on the level of the main fertilizer, we recommend the following schemes for the cultivation of corn plants:

Level of mineral nutrition Phase of plant development
3-5 sheets 8 - 10 sheets Vomiting
High N 90-120  P 90  K 90-120 Ecoline zinc 1 l / ha + Ecoline universal start 2 l / ha Ecoline Corn 1.5-2 l / ha + Ecoline Magnesium 2 l / ha + Ecoline Beer 0.5 l / ha Ecoline Corn 1.5 l / ha
Average N 90  P 90  K 90 Ecoline zinc 1 l / ha + Ecoline universal start 2 l / ha Ecobalance Line Corn 2 kg / hectare + Ecoline boron 0.5 l / ha -
Low N 60-90  P 60  K 90 Ecoline zinc 1 l / ha + Ecoline universal start 2 l / ha Ecoline Corn 2 l / ha -

Thus, due to the application of the company's products, it is possible to protect against the key harmful objects and to adjust the mineral nutrition of corn plants.
