VARIABILITY OF THE CARBON CYCLE IN SOILS OF NATURAL AND ANTHROPOGENICALLY TRANSFORMED ECOSYSTEMS OF THE KURSK REGION

The article presents data on the spatiotemporal variability of carbon pools and fluxes in Grey-Luvic Phaeozems and Albic Podzol (Arenic), as well as their various anthropogenic modifications. It was noted that the spatial diversity of CO2 fluxes from the surface of the studied Grey-Luvic Phaeozems and Grey-Luvic Phaeozems Hortic is significantly higher than from the surface of Albic Podzol (Arenic) and Albic Podzol (Arenic, Ochric). It has been established that contamination of Grey-Luvic Phaeozems and Albic Podzol (Arenic) with heavy metals has different effects on the variability of soil CO2 fluxes from their surface. It was revealed that the treatment of Grey-Luvic Phaeozems Hortic with a living culture of Chlorella sorokiniana reduces the carbon intensity of soybean cultivation technology in the conditions of the Kursk region.
