摘要
The effect of various organic fertilizers (wheat and pea straw, manure, green fertilizers-rape, clover) on gray forest soil fertility and yields in 5-field rotation has been compared with that of mineral ones-60(NPK). Organic fertilizers account for the formation of humus, nitrogen, and phosphorus pool, for the composition of neoformed humous substances and nitrites; they exert a positive effect on all the prerequisites of soil fertility (biological, agrophysical), so that they increase yields in rotation by 3.2...5.8 c/ha fodder units.
