Аgronomical assessment of efficiency of introducing various fertilizer doses for the crop rotation cultures

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.

The influence of fertilizers on the removal of nutrients by crop rotation in the Vologda region

The productivity of crop rotation on soddy podzolic loam soil in the stationary experience during 2015-2017 was high in the conditions of the Vologda region, especially among annual crops. Winter rye and potatoes also differed by consistently high yield and productivity during the years of research. All the studied cultures showed good responsiveness to fertilizers, especially the calculated doses of their application. The average productivity of crop rotation was 3.30-6.34 tonne cu / ha.
