Abstract

Currently, the global climate measurement is taking place in the world, which is directly related to the intensity of greenhouse gas emissions. The contribution of the agro-industrial complex industry to global emissions is a significant share, which is more than half. At the same time, the introduction of agriculture leads to a violation of the natural process of soil formation, a change in phytocenosis and an increase in carbon dioxide emissions. Due to the different mass of the root system, different types of cultivated plants make a diverse contribution to the formation of CO2 emissions from the soil surface. The purpose of the study is to evaluate the effect of cultivated crops and fallows on the intensity of carbon dioxide emissions in the Trans-Urals. In fields free from cultivation of crops, 6,753 kg/ha of carbon dioxide is released during the growing season. The cultivation of grain crops increases the total emissions by almost 2026 kg/ha. Cultivation of row crops at 4,979 kg/ha, which is 74% higher than the fallow field values. In alfalfa crops, 14023 kg/ha is allocated during the growing season, which is 108% higher than in the fallow field.
