FIELD: agriculture.
SUBSTANCE: invention relates to the field of agriculture, and in particular to a method for cleaning and recultivating oil-contaminated soil. The method for cleaning and recultivating oil-contaminated soils using a sorbent based on zeolite provides for the sequential introduction of natural zeolite into the cleaned soil with a clinoptilolite content of 65-70% with a fraction size of 1-3 mm and a dose of 150 g/kg of soil and a humic powder preparation based on brown coal with a humic acid content of at least 73-82% with an application dose of 15 g/m2 of soil. Further, loosening is carried out to the depth of contamination, while the soil moisture is maintained at 60% and reclamation is carried out within 4-6 months. The ambient air temperature must be above +3°C.
EFFECT: invention provides an improvement in the quality of soil cleaning in the process of reclamation, a decrease in the content of oil pollution below 1 g/kg, possibility of further use of the cleaned soil for the cultivation of crops for the next year.
