The influence of the systematic application of the same soil tillage systems in short-rotation crop rotations in the course of a long time on the change of typical fertility indices of chernozem is established. At the same time there is marked change in the density of the structure of the soil relative to the initial indices. For no-till systems, the reduction of layer density differentiation of the structure of the grant was 1.27-1.35 g / cm3, while for the discretion this index in the 0-30 cm layer of soil was within the range of 1.17-1.35 g / cm3 for plowing 1.15 - 1.29 g / cm3. The influence of cultivating systems and various precursors in crop rotation on the hardness of soil is established. No-till systems have the highest hardness of the soil, but with less differentiation in layers. In the crop rotation with a late-achieving predecessor of winter wheat, soybean in a layer 0-30 cm it was 16.3 - 19.8 kg / cm 2, for the predecessor rape rape 15.7-16.7 kg / cm2. For the minimum cultivation, the soil hardness was 8.1 - 18 kg / cm2 for the soya precursor, and for the rape was 9.3 - 17.7 kg / cm2. For traditional plowing 8.7 - 5.1 and 8.7 - 11.6 kg / cm2. Тhe highest yields in the field under study during the winter wheat rotation of 7 t / ha were obtained in crop rotation with the predecessor of rape yarim on the background of discoloration and the introduction of N120P90K100 and cultivars. At the same time, the highest profit was obtained at 28430 UAH / ha with a production cost of 2339 UAH / t.
