FIELD: oil industry and agriculture, environmental protection. SUBSTANCE: method involves biological recultivation of oil contaminated soils and waters, with low contamination extent of 3 l/sq m, average contamination extent of 15 l/sq m and high contamination extent of 30 l/sq m, by carrying out staged agronomic and phytoameliorative cleaning of lands, which must be effectuated during several years, by treating lands and waters with sorbents, mellowing, snowhedging, cultivating, applying mineral fertilizers, harrowing, sowing nitrogen gathering and salt-tolerant grasses, desalination, dealkalinization, plowing in green mass for green manure crop; effectuating during the first and subsequent years agronomic and phytoameliorative operations in predetermined sequence and combination, at predetermined time and season depending on land contamination extent. EFFECT: increased efficiency, simplified method and improved ecology control. 3 tbl |
