Abstract: This paper deals with the study results on the systematic application of fertilizers in the field crop rotation on the content of exchangeable potassium in gray forest soil. The best conditions of potassium regime in soil and rotation crop development were created by the moderate organic-mineral (12 t / ha of manure + N55P50K58) and renewable (6 t / ha of manure + N4gP30K51 + by-products) fertilizing systems. The author gives reliable their effect on the yield and improve its quality indicators.
