Zalevskyi R. Ecological characteristics and migration patterns of heavy metals in agrocenoses on the gray forest soils of Polissya.

In the dissertation work the research results about the environmental assessment of the content and redistribution of Cd, Pb, Cu, Zn in the soil are presented. The possibility of contamination of agricultural products on light-textured soils at the levels of heavy metals concentration below the maximum concentration limit is found. Fertilization systems that allow to obtain ecologically safe products for baby food and dietary under conditions of weak multielement contamination of Cd and Pb are determined. With the help of mathematical modeling a scheme of scientifically based agricultural background correction is developed, which allows correcting the rules and the ratio of organic and mineral fertilizers for the implementation of a balanced farming system in the enterprises of different forms of ownership.
