Rehabilitation of the Biological Activity of the Soil Microbiota and the Structure of the Living Cover of the Soil under Technogenic Burden of the Extractive Industry

Abstract

Abstract The article focuses on the features of the morphological, physical and chemical properties of the humus-accumulative embryo soils of nonfunctional stock heap of Mikhailovsky Mining and Concentrating Company (Mikhailovsky MCC). The biological activity of various groups of soil microorganisms: actinomycetes, microfungus and ammonifying saprophytes was studied. The types of plant communities of technogenic territory of overburden stock heap are identified, the main parameters describing the structure and dynamics of phytocenosis are described. It is established that the soils of key catena have high numbers of fungic microflora up to 145 thousand CFU / g in the gray-humus horizon, actinomycetes and ammonifiers have a low level of development. However, as relating to the previously obtained data, a general temporal tendency has been revealed, characterized by the increase in the biological activity and biomass of the groups under consideration, which is clearly observed in areas with soils rich in organic matter and mineral elements.
