CO2 EMISSIONS IN AGROCENOSES OF THE OMSK IRTYSH REGION

The results of monitoring the production of CO2 from arable soils depending on abiotic factors (air temperature, precipitation) and crop cultivation are analyzed. A comparative assessment of the fallow field and spring wheat during the growing season showed that large losses of carbon in the form of CO2 are characteristic of soils under spring wheat plants and are associated with a significant contribution to the total flow of respiration of the root system of plants during the period of intensive growth. A decrease in the emission component of CO2 was noted with a decrease in moisture availability, which is due to the inhibition of biological processes in the soil.
