Description
Summary:The monitoring studies of carbon transformation in different soil types of agroecosystems under aerotechnogenic contamination by heavy metals in years differing from the climatic norm are analyzed. The negative effects of changing environmental conditions on the content of microbial biomass and CO 2 emission in different soils have been evaluated experimentally. The ecophysiological parameters characterizing the availability of substrate and carbon (re)immobilization in soils show that the activity and stability of the microbial community depend on environmental changes. The methodology of system analysis of the intrasoil carbon cycle and the quantitative assessment of flows of net-mineralized and (re)immobilized carbon and their ratio were used for the first time for an integral assessment of the functioning regimes of agroecosystems and of the levels of the ecological load.
