Effect of physical and chemical properties of gray-brown soils contaminated with waste aluminum plant and tube-rolling mill in Sumgait on life activity of earthworms

Soil invertebrates are sensitive indicators of soil moisture. The occurrence of certain species can be an indicator of humidity or dryness of the habitat. Many researchers consider mesofauna to be one of the best bioindicators, since all actively moving species react to the slightest change in the environment by varying the number and violation of the ratios of trophic groups. To determine the main trends in soil dynamics using soil invertebrate gray-brown soils, such indicators as the quantitative ratio of individual groups, changes in the structure of the dominant representatives of the trophic structure, and distribution by soil profile are of primary importance. Special priority is given to studying the humus state of gray-brown soils associated with the pollution of natural biocenoses by technogenic waste.
