The goal of the research is to establish the parameters of indicators of fertility of the gray forest soil and the productivity of field crop rotation with various fertilizer systems in a long-term experiment. Establish the patterns of the effect of fertilizers on integrated and biological fertilizer systems in short-crop rotations with different treatments on the change in the agrochemical fertility indicators of typical chernozem. Under the conditions of stationary field experience on gray forest soil, a high level of crop productivity of a crop rotation link was achieved with an intensive organo-mineral fertilizer system - 12 t / ha of litter manure + (N60P60K68), under such conditions, an improvement in the nutritional regime, biological activity was obtained, and crop productivity link crop rotation at 6.42 t / ha Z.A. On the chernozem of the typical Panfil Experimental Station, it was determined that the grain yield in the field crop rotation with their extensive management turned out to be different predecessors of soybeans and rape - respectively, 3.45 and 3.97 t / ha. When fertilizing (intensive fertilizer system), as well as when using resource-saving fertilizer systems, the yield of winter wheat (the precursor of rapeseed) was in both cases 20 and 10% lower compared to this crop after soybean. The highest grain yield of 4.22–4.91 t / ha was in the biologization system of the fertilizer, regardless of the processing method of soybean precursor.
