The use of soil-biological methods in monitoring the soils of sand pits in the Northern taiga

Abstract

The article deals with the problem of the applicability of soil-zoological and soil-microbiological methods in monitoring young ecosystems formed in the subzone of the northern taiga of Western Siberia. It is shown that different components of the destructive link of the biological cycle are characterized by different recovery rates after the complete destruction of the taiga ecosystem. During the development of young soils in the northern taiga subzone, there is a gradual increase in the content of C-biomass, and during the first 22 years of soil formation, the content of C-biomass increases 12-fold. The restoration of communities of oribatid mites after their disturbances during the formation of quarries, in the initial period (up to 5 years after the disturbance) is relatively slow. After 22 years since the violation, the process of restorative succession is noticeably accelerated. The results of the study show that indexes of microbial biomass, abundance and species richness of oribatids in soils can be successfully used in the practice of ecological monitoring of young ecosystems forming in the taiga zone.
