Essay

Agroрhysical and рhysical-сhemical indices of black soil opodzolic, field crop rotation, organic and mineral fertilizers. The aim was to determine the effect of a long-term application of fertilizers in field crop rotation on agrophysical and physical-chemical indices of soil fertility. It has been found that 9 t of semi-rotted matter applied under 1 ha of crop rotation area together with mineral fertilizers at the rate of N45P68K36 maintain its agrophysical indices at an optimum level. The system of fertilization was improved based on the optimization of saturation levels as well as on well as on the correlation of organic and mineral fertilizers.
