The purpose of the research is to establish changes in the parameters of the humus state and the physico-chemical properties of the typical chernozem, depending on the soil cultivation and fertilizer systems in the short-rotation crop rotation. The results of studies on the content and reserves of humus, the sum of the absorbed bases and hydrolytic acidity in chernozem typical when using different fertilizer variants and treatment systems are presented. It has been established that deep waste-free processing with the introduction of straw, siderates and mineral fertilizers forms the largest reserves of humus in the soil layer 0-30 cm. The parameters of the physical and chemical properties of chernozem typical under the influence of fertilizers are improved, although by the plowing of straw, siderates and mineral fertilizers critical increase in hydrolytic acidity.
