RECULTIVATION OF OIL-CONTAMINATED SOILS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to recultivation of soils contaminated with oil and oil products. Proposed method comprises oil processing, introducing fertilisers, biological agents and sowing of grass. Note here that plowing is carried out without trenching to depth of 30-35 cm with introduction of zeolite-bearing clays, alanites, in amount of 5-6 t/hec together with minced vegetable residues of leguminous plants and leaf litter in amount of 1.5-2 t/hec and autumn planting of annul clover in amount of 25-30 kg/hec. Clover seed are pre-wetted in the solution of Baikal-EM-1 bio preparation mixed with p-amino-benzoic acid with 0.001%-concentration of every component for 2-3 h. In spring, in budding-blooming phase, bio mass is tilled into soil and herbage is pre-sprinkled with the same mix in amount of 200-300 l/hec.EFFECT: higher efficiency of soil reclamation.2 ex
