The purpose of the work is to establish the role of labile organic substances in the soil fertility and productivity of crops and to develop agrotechnical methods of influence on the content and quality composition of these substances. Research methods: laboratory methods for the study of organic matter in soil samples, comparative-analytical method, statistical processing of research results. It has been established that the non-plow tillage launches the formation of labile organic matter in the soil, which is the first reserve of nutrients for plants. The use of an intensive fertilizer system contributed to the formation of the optimum ratio of carbon labile organic substances (СLOS) to humus carbon. On the basis of the correlation analysis, a close relationship is established between the СLOS content and the crop yield; slightly smaller - between humus content and yield. The optimal content of ENT in the black soil has been established, which will allow to regulate the productivity of agrocenoses, prevent soil dehumidification and promote the fertility of the black soil. The use of these approaches are possible in the area of agriculture Product Description popup.authors Derevʺyanko Oleksandr S. Dusheyko Snizhana I. Kravchenko Yuriy S. Kucher Larisa I.
