Today, the technology of corn cultivation is not limited to the introduction of only macro-nutrients, but also involves the use of trace elements, in particular zinc, manganese, copper, boron, molybdenum and phytohormones. The value of micronutrients increases significantly in conditions of drought or periods of temperature fluctuations, stress factors or simply replenishment of the required content at the manifestations of their deficiency in plant nutrition.
In order to really benefit from endless feed, it is important to properly and skillfully apply this auxiliary food for plants using puffy diagnostics and, knowing the most important critical periods of growth and development of the culture, when the trace elements are necessary from the point of view of plant physiology and their growth phases.
On our Demo-field, which is in Prat Mshanetske, Terebovlyan district, Ternopil region. we used a scheme of non-root nutrition microfertilizers from TM Ecoorganic in the first important phase of corn growth (4-6 l), when generative organs are laid and the main root system is formed and 6-9 l, when there is an active growth of the vegetative mass with the subsequent formation of the length of the beginning and the number of grains. As a result, the yield obtained depending on the hybrid of certain groups of maturity is 8.2-12.71 t / ha (Diagram 1).

Productivity of hybrids on basic humidity and harvesting moisture.
Root nutrition on all microbial hybrids Ecoline from TM Ecoorganic:
Phase 4-6 l (30.05) - Gros coronerist, 1 l / ha + Ecoline zinc chelate, 1 l / ha.
Phase 6-9 l (16.06) - Ecoline corn, 2 l / ha + Ecoline boron premium, 1 l / ha.
Demo field technology:
seed 26.04; gathering - 17.10;
forward - oz.pshen .; plowing, 27-30 cm;
N130R78K78; density before harvesting depending on the group of ripeness - 71-87 thousand / ha;
insipidity is weak; the soil is dark gray forest; pH 6.0; precipitation for vegetation-208 mm.

At the other part of the field at the site of the hybrid P8523 (Optimum AQUAmax, FAO 260), we have been experimenting with different variants of foliar nutrition by microfertilizers TM Ecoorganic (Diagram 2).

The schemes of end-root nutrition variants P8523 microfertilizers TM Eco-orgic Control: without endless feeding.
Option number 1:
3-5 l-Ecoline Zn Chelat, 2 l / ha + Ecoline Phosphite K, 1 l / ha
6-9 l - Ecoline Corn Chelat, 1 l / ha + Gros Fosfito NP, 1 l / ha.
Option number 2:
3-5 l Ecoline Zn Chelat, 1 l / ha + Ecoline Phosphite K, 1 l / ha + Ecoline Universal Amino Growth, 1 l / ha
6-9 l Ecoline Corn Chelat, 1 l / ha + GrosPhosphit NP , 1 l / ha + Ecoline Bohr Premium, 1 l / ha.
Option number 3:
3-5 l Ecoline Zn Chelat, 1 l / ha + Ecoline Phosphite K, 1 l / ha
+ Ecoline Universal Growth Amino, 1 l / ha + GrosCorenery, 0.5 l / ha
6-9 l Ecoline Corn Chelat, 1 l / ha + Gros Fosfito NP,
1 l / ha + Ecoline Bohr Premium, 1 l / ha + Groos Health, 0.5 l / ha.
An experiment with fecal nutrition showed a good reaction of P8523. Depending on the variants of the extra root application, the yield of P8523 increased from 4.8 to 13.48%. The maximum yield increase was 1.17 t / ha.
