Abstract
Nitrogen cycles and peculiarities of spring wheat-sowed agroecosystem functioning were investigated on different types of soil polluted by fluorides from aluminum production. A disbalance between nitrogen fluxes directed towards the external and intra-soil cycles was found to be higher in gray forest soil agroecosystems characterized by the low buffer capacity with respect to fluorides than in turf-meadow soil. Stable functioning of agroecosystems on turf-meadow soil (stress regime) is maintained by intense nitrogen recirculation.
