BIODIAGNOSTICS IN ENVIRONMENTAL ASSESSMENT OF DEGRADED ARID SOILS

The article presents the results of studies on a comprehensive assessment of degraded arid soils, spread in the conditions of vertical and horizontal zoning of soil formations. The changes in biological properties under the influence of degradation processes, the changes in distribution, the number of groups of microorganisms and biochemical activity are shown. It provides criteria for biodiagnostics, which make it possible to assess the degree of general biological activity based on the values of the Integral Index of the Ecological and Biological State of Soils (IIEBSS).
