The article presents data on the spatial and temporal variability of the carbon cycle processes in different types of natural and agricultural ecosystems functioning on Grey-Luvic Phaeozems and Grey-Luvic Phaeozems Hortic. Ecological monitoring of respiration, hydrothermal and chemical properties of soil and productivity of vegetation cover was conducted in six natural and agricultural ecosystems. It was found that soils of the forest and garden ecosystems emit 7.2 – 47.9 % more carbon into the atmosphere than soils of the agroecosystems and the ecosystems with herbaceous phytocenoses. It was revealed that soils (humus horizon of 20 cm thickness) stored up to 3.3 tonnes/ha of carbon (increase in soil organic carbon (SOC) stock), while tree leaves and herbage assimilated up to 7.5 tonnes/ha of carbon in the garden ecosystem during the growing season.
