Abstract

The article presents the results of the research conducted on the sod-podzolic medium loamy soil of the Vologda Region. It reveals the effect of various doses of fertilizers on yields of major products and by-products, as well as on the feeding value of the crops in crop rotation. Fertilizer calculation systems increased yields of oat and Vicia mixture by 4.58–5.83 t/ha, winter rye by 1.02–1.50 t/ha, potatoes by 7.02–8.98 t/ha, and barley by 0.55–0.77 t/ha; crude protein collection increased by a factor of 1.6–1.8.

Keywords

fertilizers, productivity, crop rotation, crude protein.
