aref2 2 Field experiments have established a high efficiency of organ-mineral fertilizer systems using manure, providing humus reproduction in soils, improving phosphate and potassium regimes, increasing crop productivity and crop rotation in general. Organic fertilizer systems in optimizing doses have a positive effect on soil fertility, but inferior to organo-mineral systems in the yield of cultivated crops and differ little from them in the quality of plant products. The after-effects of systems in agrocenoses are manifested during the first two years in the cultivation of grain crops and more than 10 years - perennial herbs.
