STABILITY EVALUATION OF SOUTHERN RUSSIA SOILS TO CHEMICAL POLLUTION
DescriptionWe propose a method of biodiagnostics of soil resistance to chemical pollution and its regulation on the degree of violation of the ecological functions of soil based on the definition of the integral indicator of biological state (IIBS) of the soil. The comparative assessment of the stability of the major soils of the south Russian to chemical pollution are considered in this article
