The structural condition and structure of the arable layer of typical black earth in various systems of the basic processing and fertilizers in specialized seed rotary of crop rotation of central Forest-Steppe of Ukraine

Abstract

We have investigated the influence of longitude effect of different systems of the main processing of soil and different fertilization levels on changes of agrophysical and agrochemical properties of typical black earth and productivity of specialized grass and grain plowed crop rotation. We can observe higher indexes of soil productivity of arable layer of soil of typical black earth in Forest-Steppe of Ukraine after its three-year use in the duration of shallow treatment compared to subsurface tillage and longitude surface tillage. We recommend deep (25–27 cm) tillage on one part and a shallow one (10–12 cm) on the rest parts in a five-part crop rotation.
