Abstract
The application of agrogeochemical technologies aimed at restoring agrogeochemical cycles in agricultural ecosystems, primarily in the microbial link regulating CO2 flows, is considered. Examples of recultivation of disturbed and polluted soils, waterlogged and/or over-dried soils are given and their impact on the amount of CO2 flux is estimated. A complex of agrogeochemical technologies aimed at assessing and stabilizing the microbial link of the biogeochemical cycle in agroecosystems is presented. Examples of the use of these technologies for the regulation of CO2 emissions in agroecosystems are given. Using one of these technologies, an almost 5-fold decrease in the rate of CO2 flows during the reclamation of disturbed pasture ecosystems of the tundra is shown. It is necessary to further develop and use agrogeochemical technologies aimed at restoring biogeochemical cycles in agroecosystems, primarily in the microbial link regulating CO2 flows.
