Degradations and stability of nonchernozem soils to oil contamination in the conditions of the south west Russia
In the conditions of the south-west region of Russia oil in the quantity of 4-32 l/m2 staying for 6 hours and 1 year on the surface of the soils causes their system degradation. Degradation degree depends on the amount of the poured oil. Oil contamination of soddy-podzolic soil for 6 hours in the quantity of more than 4 l/m2, and for 1 year - more than 8 l/m2 and of grey forest soil - more than 32 l/m2 has catastrophic effect on the soils.
