FIELD: process engineering. ^ SUBSTANCE: invention relates to biotechnology, particularly to environmental protection and can be used for purification of soil from hydrocarbon contaminants. Proposed method comprises seeding plants, phytoremediants, into soil. In compliance with first version, prior to seeding, seeds are treated by suspension of strain Sinorhizobium meliloti P221 or Azospirillum braselense SR80. In compliance second version, proposed method comprises seeding phytoremediants and soil inoculation by suspension of strain Sinorhizobium meliloti P221 or Azospirillum braselense SR80. Note here that inoculation is performed to produce concentration of 1 - 3*107 cells/g of soil contained in surface layer with depth of up to 30 cm. Said phytoremediants represent mix of seeds of pod-bearing plants, namely Lucerne, and seeds of cereals, namely ryegrass, and/or winter rye and/or sorghum in ratio of 1:1-3. ^ EFFECT: higher efficiency. ^ 2 cl |
