Ecological Systems and Devices Annotation << Back Soil microorganisms in conditions of petropollution Chernykh N.A., Batovskaya E.K., Baeva Yu.I., Golovin V.G The information about oil and mineral oil influence on a complex of soil microorganisms, its quantity, specific structure and functional integrity is offered. The research of some parameters of biological activity for various types soils (sod-podzol, chernozem and light-brown) is realized. The most sensitive soils to high concentration of crude oil are chosen. The regularities for change of quantity of the microorganism basic groups are obtained under different levels of soil pollution.
