THE INFLUENCE OF PHYSICAL PROPERTIES OF CHERNOZEM SOIL ON THE ACTIVITY OF SOIL ENZYMES
In 2019, studies were conducted to determine the effect of the physical properties of the black earth soils of the Stone Steppe on the activity of soil enzymes. The activity of soil enzymes phosphatase, invertase, urease is higher in the soil naturally preserved biocenosis in comparison with the soil of agrocenosis. Catalase activity is higher in the soil of agrocenosis than in the soil naturally preserved biocenosis. The highest activity of soil enzymes was shown in the fractions of a smaller size. By regulating the physical properties of the soil, one of which is the structural state, it is possible to influence both the number of microorganisms and the number of soil enzymes peculiar to it.
