INFLUENCE OF ANTHROPOGENIC NITROGEN EMISSION ON BIOLOGICAL -GEOCHEMICAL PROPERTIES OF SOILS AND SPECIES RICHESS OF GROUND VEGETATIONIN MEADOW ECOSYSTEMS
In the meadow of the industrial zone (10, 15, 20 m, total 9) of the NAK «Azot», Novomoskovsk city and at a distance of 5 and 20 km (5 in total) from it in the background of the Novomoskovsk district, Tula region the species composition of the ground cover was assessed and the upper humus layer of soils(0-20 cm) was selected. The content of ammonium (N-NH +), nitrates (N-NO -),4 3ПЭММЭ, Том ХХVIII, № 4, 2017total carbon (Ctot) and nitrogen (Ntot), P, Al, Ca, pH, texture, as well as microbiological properties (microbial biomass carbon (Cmic), microbial respiration (MR), microbial metabolic quotient ( q CO2) and part of Cmic in the total pool of Corg). According to the results of the study, it was found that in the industrial zonethere were a decrease in the Ntot / P ratio in the soil, but an increase of the content3micof Nmin, N-NO -, Ca and Al and the indicators of its microbial community (C,MR, Cmic /Corg, q CO2), as well as an increase in the species richness of bryophytes in the ground cover.
