It was determined that the extended reproduction of the fertility of gray forest soil with the systematic application of various types of fertilizers was achieved with organo-mineral (12 t of cattle manure per 1 ha of crop rotation area + N80P60K80) and organic (12 t/ha of cattle manure) fertilization systems and with the application of 1 t/ha of OMBD - 4-4-4. It was established that the yield increases under modern fertilization systems for growing oats were 36–54%, barley 38–45%, and buckwheat 29–36%, with the yields in the control, respectively, - 3.42, 2.70 and 1.92 t/ha. The economic feasibility of using optimal doses of mineral fertilizers N40Р30К40 on the background of cattle manure - 12 t/ha of crop rotation area, organo-mineral bioactive fertilizers of the 4-4-4 brand in doses of 1 t/ha and 0.5 t/ha + N40 was determined, where the level of profitability for growing oats was within 74–89%, spring barley 41–107% and buckwheat 69–98%. Compared with traditional intensive fertilization systems, the economic efficiency of ecologically balanced ones in terms of profitability indicators on average for crops exceeds 45–60%. It was determined that the energy efficiency coefficients for the optimal fertilizer options were 3.9-5.5 for oats, 3.4-4.3 for barley, and 2.0-2.7 for buckwheat, and exceeded traditional intensive ones by 35-50%.
