Аннотация:A field model experiment on stimulating the activity of native oil microorganisms–decomposers
was performed on an oil-polluted area in a high-moor bog under its total flooding in the northern taiga (Western
Siberia). For two summer months, the doses of lime and nitrogen, phosphorus, and potassium fertilizers
applied have caused a decrease in the oil products (OP) content by 54% relative to their initial amount. The
decrease of the OP content in the soil profiles was nonuniform, and at the depth of 30–50 cm it was accompanied
by the acidification of peat. The stimulation of the activity of aboriginal microorganisms by applying
lime and mineral fertilizers led to the development of migration processes with the participation of oil and
products of its transformation. These processes differed from those in the soil without application of lime and
fertilizers. An original technology of applying lime and fertilizers providing minimal disturbances the upper
50-cm peat layer is suggested.
