The essential part of a soil cover of the Republic of Adygea is occupied by gray forest soils. Thus they still remain a little studied, including concerning their resistance to chemical pollution. Contamination of gray forest soils of Adygea with Zn, Cd, Mo, Se causes deterioration of their biological properties. In most cases, the degree of reduction of the values of biological indicators is directly dependent on the concentration of pollutant in the soil. According to the degree of toxicity to the biological properties of the investigated elements form the following sequence: Se > Zn > = Cd > Mo. Biological parameters investigated in research (activity of catalase and dehydrogenase, cellulolytic ability, abundance of bacteria of the genus Azotobacter, radish root length) may be used for purposes of monitoring, diagnosis and regulation of chemical pollution of gray forest soils Zn, Cd, Mo, Se
