Air Pollution and Climate Change
The problem of carbon dioxide emission from the soil is relevant, since it affects the reduction of the soil organic carbon pool, thereby reducing its fertility and productivity. In addition, carbon dioxide emissions from the soil are a significant contributor to the greenhouse effect. The aim of this work was to evaluate the mineralizing activity of the microbial community of the soil of a new point of observation of carbon dioxide emissions, located in the previously little-studied territory of Russia, using such parameters as respiration activity, microbial biomass, and the number of copies of bacterial and fungal genes. The highest values of respiration activity and microbial biomass of the studied soil were 2.3*10-4 mgCO2*g-1*h-1 and 0.48 mg*kg-1 and were observed on 26.07.2022 and 15.06.2022, respectively. The maximum number of gene copies of bacteria and fungi in the soil was 6*106 (15.06.2022) and 3.78*104 (15.06.2022) gene copies*g-1, respectively. It was revealed that the respiration activity of the soil depended on the air temperature and soil moisture, while the microbial biomass depended mainly on the air temperature.
