ANALYSIS OF BIOLOGICAL ABSORPTION COEFFICIENTS OF HEAVY METALS FOR FODDER BEET

Abstract

The results of a field lysimetric experiment on podzolized сhernozem to study the coefficients of biological absorption of heavy metals and trace elements for root crops and tops of fodder beets using various systems of mineral fertilizers are presented. Analysis of the empirical series of accumulation of elements in the main and byproducts of fodder beet plants showed that the level of accumulation of zinc, lead and cadmium in root crops is significantly lower than in the tops, and the copper content is relatively evenly distributed between the main and by-products according to the variants of the experiment. In the variant with an increased agrochemical background, there was a decrease in the content of copper, zinc and lead in the main and by-products of feed beets, which may be due to the effect of biological dilution when using mineral fertilizers.
