Sivkov Yuri Viktorovich  (Ph.D., Associate Professor, Tyumen Industrial University)

The paper presents the results of field studies of various variants of bioremediation of oil-contaminated meadow soils. The effectiveness of the studied methods was evaluated both directly - by reducing the level of residual content of petroleum products, and indirectly-by assessing the phytotoxicity of selected samples in the laboratory. As a result of the conducted research, the residual content of petroleum products was reduced depending on the applied scheme from 47.52 to 70.82 %. The method of combination of a biological preparation and a sorbent (vermiculite) showed the greatest efficiency. However, when assessing phytotoxicity, the best results were shown by the site where the biopreparation was used in combination with potassium HUMATE.

Keywords:bioremediation, phytotoxicity, oil pollution, soil, humates.
