Recently, there has been an active development of all industries, transport, agriculture within the steppe zone of southern Russia. The agro-industrial complex is widely developed within the Rostov region, characterized by highly efficient crop production, grain and sunflower production. The article examines the soil cover and agricultural products of the region. A change in the distribution of trace elements in the upper soil layer with the use of various agricultural technologies was revealed. It was revealed that the most favorable conditions for the accumulation of most of the studied microelements are formed in the soils under rice fields and vineyards. In the course of the research, the differentiation of the main crops for a number of heavy metals was studied. An analysis of the data obtained indicates the existence of a tendency for the average content of trace elements to increase from grain crops to forage grasses, which is associated with soil conditions and specific biological characteristics. According to the content of elements in soils, the coefficient of biological absorption and biogeochemical activity of the studied crops were calculated, which made it possible to rank them according to their ability to accumulate heavy metals.
