The climate changes of recent decades are mainly due to human activities and an abnormal increase in greenhouse gas concentration in the atmosphere. Carbon dioxide released by the soil during emission is of particular importance. Soil carbon dioxide emissions are closely associated with the microbiological activity of the soil and the intensity of the mineralization of organic matter, which depends on the technologies used in agriculture. One of the ways to reduce the level of CO 2 in the atmosphere is to increase its content in soils. Based on experimental studies, the paper provides a comparative assessment of methods of soil use influencing the intensity of soil CO 2 emission under a moderately arid and forest-outlier steppe of the Altai Krai. The paper reveals that the traditional technology of soil use significantly enhances the intensity of CO 2 emission. It negatively affects the humus state and soil fertility indicators and increases carbon dioxide content in the atmosphere. The use of minimal technology contributes to the conservation of carbon in the soil.
