Ways to increase the biogenicity and fertility of the soil cover of oil-polluted landscapes

The article is devoted to - studying the impact of oil pollution (Siyazanneft field) on the dynamics of microbiological processes in the soil and the identifying of the possibility of reducing amount of hydrocarbons in the soil cover using biotechnology methods, in a controlled mode. In the series of model experiments, the effect of the various additives and the prepared bioproduct to the decomposition of hydrocarbons and the biological activity of oil-contaminated soils was studied. In a model experiment introduction of ameliorants into contaminated soil, separately and together, contributed to increasing of the general biogenecity of soils and the decreasing of the oil content in the soil by 17-62% compared to the control. These biotechnologies can be very effective in the development of bioremediation technologies for oil-contaminated soils.
