The calculated fertilizer systems have significantly increased the yield of the Volkhov winter rye in grain by 52-67% and in straw - by 50-59% on the soddy podzolic medium loamy soil of the Vologda region on average for three years of research. Applying fertilizers at the rate of 1cwt/ ha in physical weight when sowing during two years out of three ones has provided a significant increase in the yield of winter rye grain. When using the calculated doses of fertilizers, phosphorus and potassium yields by a unit of production has been slightly below the planned values.

On the sod-podzolic medium-loamy soil of the Vologda region, the calculated fertilizer systems have increased productivity by 30-94% on average for 3 years of the research compared to the no-fertilizer option, by 33 - 49% compared to the sowing fertilizer (for cereals and annual crops and applying fertilizer when planting for potatoes). The use of fertilizers provided a high cost of 1kg of active material by productivity gains of all studied crops, and for the research years there has been the highest cost - 23 kg of fodder units. The calculated doses of fertilizers have differed in cost.
