Absorption capacity of soils in anthropogenous territorial complexes of the Donetsk-Makeyevka industrial agglomeration

In the soils of anthropogenous transformed ecosystems (monitoring sites № 2, 7, 8), values of total exchangeable bases varied within 33.6–56.9 % in relation to control. The indicator of the sum of exchangeable bases in the soils of rock dump ecosystems (monitoring sites№3–6) was significantly lower both in relation to control and in relation to the sum of exchangeable bases in the soils of anthropogenous transformed ecosystems. Compared to control, the content of exchangeable calcium and magnesium in soils of all monitoring sites is reduced, which indicates unsatisfactory conditions for the vital activity of microorganisms and functional activity of the soil. Experimental sowing of phytorecultivants has affected the total of exchangeable bases and the content of exchangeable calcium and magnesium in case of sowing of both monospecies and multispecies groups of plants, but the maximum values of these indicators were noted when using polycomponent grass communities.
