Abstract: The article presents estimates of the specific emissions of carbon dioxide released by the soil of land resources in Russian regions. The estimates are compiled based on the T&P model of American scientists J. W. Raich and C. S. Potter. When compiling estimates using the model formula, hydrothermal parameters of the regions of the Russian Federation were used: average monthly temperature and average monthly precipitation during the growing season, which begins and ends at an air temperature greater than or equal to 5°C. The tables of estimates include the first and last months of the growing season, as well as the average monthly air temperature and average monthly precipitation during the growing season of the region. Specific emission table is the subsequent input information for the multiple linear regression equation, which, similar to the T&P model, can be used to calculate specific carbon dioxide emissions in the regions of the Russian Federation. The coefficient of determination of 0.88 of the multiple linear regression equation reflects the high dependence of the function: specific carbon dioxide emissions in the region by the studied factors: average monthly air temperature, average monthly precipitation during the growing season and the duration of the growing season. The article provides evidence of a more significant (9.4 times) influence of the average monthly temperature factor on specific emissions compared to the factor of average monthly precipitation. Estimates of specific carbon dioxide emissions in the regions of the Russian Federation can be used in compiling the soil carbon balance in the region to develop directions for the development of agricultural and non-agricultural production with a low carbon footprint and maintaining a stable state of soil fertility.
