FIELD: chemistry.
SUBSTANCE: invention relates to bioengineering and specifically to compositions for cleaning soil from oil contamination. The composition contains peat as an adsorbent and a source of oil-oxidising microorganisms and nitrogen-phosphorus-containing fertilisers, and additionally contains zeolite, 100 g of the absolutely dry substance (a.d.s) of the composition containing 5-10% zeolite, 8.0% gold and 1.2% phosphorus, with the following ratio of components in wt %: nitrogen fertiliser 15.9-23.5; phosphorus fertiliser 5.3-6.1; zeolite 5.0-10.0; peat (a.d.s) - up to 100.
EFFECT: invention increases efficiency of cleaning soil from oil contamination.
