Yakovleva L.V., Utaliev A.A. AGRI-ENVIRONMENTAL EVALUATION OF TOTAL NITROGEN CONTENT IN SOIL — VEGETATIVE COMPLEXES OF THE ASTRAKHAN REGIONIn the work features of receipt and accumulation of nutritious phosphorus in soil-vegetative complexes of meadows of medium and lower levels of delta of Volga are considered. Dependence of formation of vegetative communities on position in a relief and humidifying degree is established. The data about accumulation of phosphorus in soil-vegetative complexes of meadows of medium and lower levels is obtained, it is established that their concentration in many respects depends on specific structure of vegetative communities, their position in a relief and distinction of physical and chemical characteristics of a soil cover. For not embanked sites higher maintenance of phosphorus in elevated parts of plants is peculiar, and embanked territories are characterized by higher maintenance of phosphorus in tree waste and underground parts of plants.Key words: nitrogen, soil fertility, deltoid territory, hydromorphic soil, biogeocenose, soil.
