Abstract
The paper presents the results of lysimetric experiment on podzolized Chernozem to study the coefficients of biological absorption of heavy metals and trace elements for buckwheat phytomass using various systems of mineral fertilizers. Analysis of empirical accumulation series showed that buckwheat phytomass accumulates zinc and cadmium more intensively than copper and lead. In the variant with optimal doses of mineral fertilizers, the content of zinc and lead in buckwheat phytomass decreased, which may be due to the effect of biological dilution when using mineral fertilizers.
