Content of heavy metals in the system "Soilplant" of garden agrocenosis in Tambov region
The paper deals with the results of research on the agrochemical characteristics and assessment of soil contamination by heavy metals, as well as on the accumulation of heavy metals in garden agrocenosis on dwarf clonal rootstocks under conditions of Tambov region and their distribution in the system "soil-plant", as well as in the organs of apple trees. The research revealed that the accumulation of heavy metals in roots was the highest. In stem, leaves, root vegetables and tubers, they were accumulated in equal quantities. Such elements as zinc, cadmium, manganese and molybdenum are absorbed and accumulated most easily in edible parts of plants. The absorption of lead, mercury and chrome is quite limited. It was found that transplantation of metals from soil into a plant depends not only on soil characteristics but biological properties of plants and their physiological condition.
