Abstract

In the field technological experience on sod-podzolic sandy loam soil it was found that the most agroeconomically effective was the N45+30P45K75 application on the background of straw with non-root treatment with Agropon С growth stimulant: the yield was 11.3 t/ha, conditional net income - 485 USD/ha, profitability - 174 % at the cost of 1 ton of corn grain gain 47 USD. With this system of fertilizer, the content of humus and mobile forms of phosphorus and potassium for the years of study remained at the initial level or close to the one.
