Abstract
The impact of contamination by fluorides from aluminum smelters on agroecosystems and their components (soils, microorganisms, plants, and the atmosphere) has been studied. Fluoride has a stronger effect on the gray forest soil in comparison with the alluvial soil, which is reflected in a drop in the soil buffer capacity with respect to fluorides and in the functioning of agroecosystems and their components. The disturbance of carbon and nitrogen cycles in the contaminated soils is related to the enhanced mineralization of organic matter and lower nitrogen reimmobilization. The stability (ecological equilibrium) of agroecosystems depends on the equilibrium of nitrogen fluxes.
