Phosphoric and potash fertilizers added to anthropogenic-transformed peat soils in P₉₀K₁₂₀ doses for perennial legume-cereal grasses provide profitability of milk industry of 95 %, if the dose is increased up to 180 kg per ha, the profitability of 108 % will be obtained. Dose of K₂₄₀ reduces profitability to 107 %, despite the increase in benefit in relation to P₉₀K₁₈₀ variant. Fractional application of N₆₀ (30 kg per ha nitrogen fertilizer under the first and second cuttings) on P₉₀K₁₈₀ base is recognizes as more profitable method for perennial legume-cereal grasses which are used in milk industry. Benefit is 1172.84 rub. per ha (591.1 U.S. dollar per ha), profitability of production is 119 %.
