In order to determine the optimal combination of components of a fertilizer system economic and agronomic efficiency of lime, organic and mineral fertilizers in grain and steam crop rotation in the forest steppe of the Trans-Urals was analyzed. The definition of agronomic efficiency showed that the payback of 1 kg of active ingredient (a.i.) of added fertilizers yield gain on average over 3 years made 1.04-1.42 kg, the maximum payback was observed in the option with a dose of N30P30 – 5.33 kg of grain units (g.u.)/kg a.i. The increase in the dose of mineral fertilizers increased the production costs and reduced the payback from 2.12 to 1.49 rubles. Options of mixed organo-mineral fertilizer on the basis of sapropel with lime and mineral fertilizers in the ratio of mass fractions 1:0,1:0,01 and 1:0,1:0,05 are proposed.
