Impact of technogenic edaphotopes recultivation on the functioning of soil microorganism communities involved in the transformation of nitrogen compounds

The mining and technical recultivation of technozems contributes to the restoration of the numerical composition of the community of soil microorganisms that take part in the processes of nitrogen compounds transformation. This is evidenced by the restoration of the number of organotrophic bacteria of the nitrogen cycle to 0.3 million CFU/g of soil and a 2–3 times increase in the number of streptomycetes in the surface layers. The increasing indicators of microbiological transformation and mineralization of organic compounds in technozems confirm the restoration of their biogenicity during recultivation, which contributes to the intensification of mineralization processes and the absorption of nitrogen compounds by plants in the soil.
