With the development of anthropogenic activities, heavy metal influence of soil agroenvironment occurs, which consequently reflects on the health of organisms. In terms of the possible effects of natural/anthropogenic agroenvironment on the health of organisms, it is necessary to remember that element bioavailability is a more important factor. The aim of this research was to analyze and evaluate the soil under sugar beet, to determine the concentrations of selected heavy metals in the soil and assess the risk of their bioavailability for sugar beet. Soils are reliable indicators of environmental qualities. The analyses of the soil samples were carried out by the AAS method using the seven-step SSE by Ziehen & Brümmer (14). The SSE method is a suitable procedure, which allows solving various agrochemical element contamination problems. The total concentration of Cd in the soil was 1.26-2.83 mg/kg, Mn was 585.58-869.53 mg/kg, Ni was 27.44-46.24 mg/kg, Pb was 25.705-40.52 mg/kg, Zn was 60.0-108.36 mg/kg of dry matter. The available forms of Cd represented 64% share, Mn represented 77% share, Ni represented 29% share, Pb represented 52% share, Zn represented 12% share. The 4th fraction was mainly dominated by organics.
