The article presents the results of experimental studies of the influence of organo-mineral fertilization systems on the agrophysical properties of gray forest soil and the productivity of row crops in short-rotational crop rotations. It was established that higher values of field and productive moisture, lower values of the density of the soil environment during the entire growing season are ensured by the traditional fertilization system with the introduction of N120Р100К100 for corn and N90Р90К90 for potatoes against the background of 40 t/ha of manure. An alternative system that involves the replacement of the traditional organic component – manure – with a complex combination of the green mass of the postharvest sideral culture of oil radish and by-products of the predecessor in the crop rotation – winter wheat and the same doses of mineral fertilizers optimizes moisture reserves and the density of the soil environment at a lower level. Organomineral fertilization systems ensure an increase in the yield of corn grain in a grain crop rotation by 1.6-1.8 times, potato tubers: in a crop rotation – by 2.1-2.5 times, in a grain-row crop rotation – by 1.9-2.4 times compared to unfertilized options.
