Abstract:Presented research results for content of the trace elements in soil and vegetation of the Tyumen federal wildlife preserve. Using the atomic absorption spectroscopy the content of the movable form of 8 trace elements in ground was determined (acetate ammonium buffer used as extraction agent, рН — 4,8) as well as the content of these elements in plants of the Tyumen federal wildlife preserve. Shown that the content of movable forms of virtually all of examined elements in soil of the Tyumen federal wildlife preserve varies in a small range, while the content of movable forms of Zn, Cu, Co, Ni, Pb not exceeded the maximum permissible concentrations. Stated that content of trace elements in plants are varied in a wide range and determined by the specific peculiarities of plants. By calculating the percentage of samples with excessive and insufficient concentrations of trace elements we obtained some series reflecting regularities of trace elements accumulation in the ground of wildlife preserve. It was discovered that the most concentrating element in plants of the Tyumen federal wildlife preserve is nickel then manganese and cadmium, while plants have not enough provision of iron and copper. Shown that there are no significant problems with the ecological situation in Tyumen federal wildlife preserve, as no excessive concentrations of examined trace elements was detected. However, found some insufficiency of iron and copper in plants which can be eliminated by applying micro-fertilizers with such elements in stern grass vegetation areas for winter additional fourage for animals.
