Tsentylo L. Agroecological Bases of Chernozem Typical Fertility Restoration and Increase of Agrocenosis Productivity of the Right-Bank Forest Steppe of Ukraine

The dissertation thesis is devoted to the theoretical substantiation and experimental solution of the scientific problem of increasing chernozem typical deep fertility using fertilizer systems, tillage and increasing crop productivity of the RightBank Forest Steppe of Ukraine. The informativeness and objectivity of composting, which is a complex interaction between organic matter, microorganisms, moisture and air, have been theoretically substantiated and experimentally confirmed. Microbial activity is enhanced by providing the required level of moisture and oxygen. In addition to oxygen, microorganisms also need nitrogen, phosphorus, potassium and the presence of trace elements. These substances are contained in manure, various wastes. Improved agrotechnical measures aimed at reducing the energy intensity of tillage, increasing the economic efficiency of crop rotations on the background of fertilizer systems, the impact of basic tillage and fertilizer systems on the dynamics of the number of microorganisms, the content of nutrients and humus in the soil.
