Abstract
In monitoring studies (1992-1997), an estimation of CO2 emission from arable soils in fallows an winter wheat sowings has been carried out. Its dependence on hydrothermal conditions, and a correlation with humus content and the magnitude of gaseous carbon losses have been demonstrated. The causes of the increase of CO2 emission from the soils under the conditions of technogenous pollution are discussed. It is found that the cointribution of direct local technogenous CO2 discharges into the atmosphere is not considerable as compared to the indirect influence of pollution on the increase of CO2 from soils in agroecosystems
