FORMATION OF SOIL STRUCTURE OF CHERNOZEMS IN DIFFERENT AGROECOSYSTEMS

In order to preserve the satisfactory functioning of agroecosystems of the Left Bank of Ukraine in the context of global warming, based on the results of soil structure formation studies, proposals can be made for the reproduction of fertility , protection of chernozem soils and rational land use. Soil organic matter and soil biota have a leading influence in soil structure formation. It is established that the best structured variants of agroecosystems with the addition of organic and organo-mineral fertilizers. Such agrochernozems have the highest content of organic soil and the highest biogenicity indicators. The biogenicity index is calculated by the percentage of the number of ecological and trophic groups of microorganisms.
