The complete organo-mineral fertilizing system (N21-63P64K122 with 8 t/ha straw manure) provided a grain-row crop rotation productivity of 10.16-10.55 t f.u./ha, an NPK repayment of 8.0-8.7 f.u./kg, and a mineral fertilizer profitability of 41-48%, with the reproduction of available phosphorus and potassium in the plow horizon of sandy-loamy soddy-podzolic soil.
