Biological properties of soils of the "Nadedzhdinsky" and "Severo-Kamyshansky" oil fi elds located in the territory of the "Mekletsky" reserve

The most acute environmental problem in many regions of Russia and other countries is environmental pollution with oil and oil products. Soil pollution with oil products can occur in various emergencies in areas of oil production and processing, when oil pipelines break, which causes leakage and spills on the soil surface, as well as in places where oil products are distributed. The purpose of this study is to study the biological properties of soils in Kalmykia under conditions of oil and oil products pollution.

мChange of Ecological and Biological Properties of Light Brown Soils of Kalmykia at Oil Pollution

Change of ecological and biological properties of light brown soils of Kalmykia at oil pollution is investigated. Negative influence of oil pollution on biological properties of light brown soils is studied. Influence of oil pollution on body height and development of plants is studied. Oil negatively influences such indicators of plants as the root length, the stalk length, the quantity of the sprouted plants, they decrease. It is proved that oil pollution of the light brown soil leads to change of physical and chemical properties of soils.
