Assessment of efficiency of crops various phytoremediants for restoration of the oil polluted gray forest soil

The paper presents data on the study the effectiveness of various crop plants for remediation of oil-contaminated gray forest soils. Assessment of the cleaning and restoration of soil ecosystems based on the use of a total content of residual hydrocarbons and the complex of biochemical (enzyme activity) and microbiological (the number of different physiological groups of microorganisms) parameters in the rhizosphere of plants. All figures have been merged into a common integrated indicator of biological activity in the soil. Our studies allow us to recommend as phytoremediants alfalfa seed and rump inermis.
