FIELD: process engineering.
SUBSTANCE: invention relates to agriculture. Proposed method comprises application of natural sorbent with biological preparation into soil to preset concentration of contaminant in soil. Note here that said sorbent represents a green earth while biological preparation represents polycultures. Prior to said application, concentration of contaminant and sorbent weight are measured. After measuring concentration of contaminant in soil at the boundary of its penetration therein, shielding layer of biocompost is placed at contaminated layer bottom. Wetting of contaminated soil is performed after distribution of sorbent with biocompost over contaminated soil with simultaneous mixing. Note here that contaminant concentration is determined layer by layer. Note also that the number of contaminated soil layers with contaminant concentration differing by two times makes, at least, two.
EFFECT: efficient decontamination.
