The ecological and economic evaluation the remediation technology of oil-polluted lands by using effective biological preparation

The article describes results of pilot tests of remediation the oil-polluted lands with use the efficient biological preparation, contains active strains of soil microorganisms, which has the production-valuable properties due to the high content of humic, carbon, aminoacids, polysaccharides and vitamins. The technology allows to reclaim oil-polluted soils, which are represented by loam, clay, and sandstone by a single treatment with a biologic for one summer season at the lowest cost.
