Russian. The steppe zone of the south of Russia is a territory in which all sectors of industry, transport, agriculture are actively developing. The agro-industrial complex, represented primarily by highly efficient crop production, is widely advanced within the Rostov Oblast. The article examines the soil cover and agricultural products of the region. Changes in the distribution of nickel and vanadium in the upper soil layer when using different agricultural technologies were studied. It was revealed that soils under meliorated landscapes form favorable conditions for vanadium accumulation and nickel extraction. When studying the differentiation of the main crops on the ability to accumulate these microelements, the tendency to their accumulation in vegetable crops, in particular in beets, was noted. Using the content of elements in the soil, the coefficient of biological absorption of the studied crops was calculated, which allowed to estimate the level of accumulation of heavy metals by them.
