The purpose of our research was to determine the qualitative state of soils and phytocenoses in the livestock enterprises areas for studying the ability of various plant species to fix and remove heavy metals from contaminated soil elements for using these plants for soil phytoreclamation in erosion hazardous areas. The research was carried out in Rostov region in the gully of the educational establishment “Donskoe” of Don State Agrarian University in Oktyabrskiy District of Rostov Region, where soil and plant samples were selected for further analysis for the content of heavy metals. It was found out that in the green top the highest content of lead (0.24 mg/kg) and zinc (43.3 mg/kg) was noted in the sumpfweed (Cyclachaena xanthiifolia Nutt.); cadmium (0.09 mg/kg), nickel (2.9 mg/kg), cobalt (0.3 mg/kg) and manganese (80 mg/kg) were noted in common orache (Atriplex patula); iron (252 mg/kg) and copper (8.2 mg/kg) were found in the wheatgrass (Elytrigia repens L.). In the roots, the greatest amount of lead (0.74 mg/kg), cadmium (0.11 mg/kg), zinc (147.0 mg/kg), manganese (90.0 mg/kg) and copper (64.0 mg/kg) was observed in the wheatgrass; nickel (6.0 mg/kg) was in the common orach (Atriplexpatida); cobalt (0.82 mg/kg) and iron (1780 mg/kg) were found in the sumpfweed. It has been determined that the most promising of the studied plants for phytoreclamation of soils under biogenic contamination are wheatgrass (Elytrigia repens L.) and sumpfweed (Cyclachaena xanthiifolia Nutt.).
Key words: heavy metals, biogenic elements, ecological systems, soil phytoreclamation, pollution by biogenes, erosion-hazardous territories.
