ABSORBENT CAPACITY OF SOILS OF TECHNOGENOUS DISTURBED LAND IN DONETSK-MAKEEVKA INDUSTRIAL AGGLOMERATION AS AN INDICATOR OF INITIAL STAGE OF SOIL FORMATION
The article presents results of the study of soils absorption capacity in technogenous disturbed lands of Donetsk-Makeevka industrial agglomeration. It is shown that the exchangeable bases in a small amount are contained in the rock dumps of coal mines and in the embryozem of dump-pit complexes, which certainly affects the content of exchange bases in the SAC, the concentration of which was significantly lower than the control level. The exchange and hydrolytic acidity values of technozems have increased compared to similar genetic horizons of the control site, which may be one of the limiting factors of the process of soil formation of technogenically disturbed lands.
