Annotation:

The article presents the results of studying brines influence on the state of the soil cover and soil salinization on the soil biocenosis. It is shown that highly mineralized formation waters, which are revealed during the extraction of mineral raw materials, negatively affect the biological activity of the soil; the quantitative and qualitative composition of soil organisms and thereby significantly reduce the level of soil fertility indicator. The changes that occur are caused by the ingress of concentrated brines and are characterized by changes of the structure, composition and content of chemical components in the soil.
