Abstract

Vegetation takes the active part in processes of migration and transformation of chemical combinations on the Earth's surface. The intensity of biogenic migration of chemical elements is defined, first of all, by chemical composition of plants. Various security of soils with chemical elements causes also their various accumulation in agricultural plants. Unrationed use of fertilizers, pesticides, broad development of the industry in the territory of the studied region - all these factors allow to classify the Rostov region as a risk group for agricultural products. The Rostov region is one of the largest agrarian regions of Russia which is characterized by high-performance agriculture. The majority of its territory is busy with agricultural grounds, presented by generally arable grounds. Within these territories such crops as grain and leguminous, technical, vegetables, fruit and fodder herbs gained the development. Since 2005 along with the geochemical researches of soils geochemical approbation of the main crops which are grown up in the territory of the area was carried out. In the course of the research specific differentiation of the main crops by nickel and vanadium, grown up on different types of soils was studied. It was revealed that the increased accumulation of elements in grain crops happens in vegetative bodies. Using the contents of elements in soils, the coefficient of biological absorption and the index of bio-accumulation of these metals in different types of vegetation were calculated that allowed to make their ranging on ability to accumulation of Ni and V.
