The article presents the results of a comparative analysis of CO2 emissions from the soils of deciduous (Upland Oak forest) and coniferous (Usman Pine forest) forests in the Voronezh region. Using the substrate-induced respiration method, the contributions of autotrophic and heterotrophic components to the total carbon dioxide flux were quantitatively assessed. It was found that root respiration predominates in oak forests, while microbial respiration predominates in pine forests. The differences are due to the structure of the phytomass, moisture content, and carbon reserves in the soils.
