Evaluation of the stability of brown forest soils of the Adyghea Republic foothills to pollution with toxic microelements according to biological indicators
Contamination of soils in foothill forests of Adyghea Republic with zinc, cadmium, molybdenum or selenium deteriorates the biological properties of the brown forest soils. The conducted research has shown that the degree of reduction of biological indicators is directly dependent on the concentration of pollutants in the soil. According to the degree of toxicity to the biological properties of brown forest soils the elements under study form the following sequence: Zn > Cd > = Se > Mo.
