Different capacities of soils for heavy metal adsorption affects the absorption of heavy metals by plants. The present study was conducted to obtain quantitative information about the heavy metals forms in chernozem and chestnut soil and their translocation in barley.

The availability of heavy metals in soils was characterised by various extraction procedures. After differentiating soil zinc, lead and copper into exchangeable and dissoluble by weak acids, organic complex bound, amorphous compound and carbonate bound forms, a regression equation model was presented relating zinc, lead and copper contents in corn of barley to the three soil zinc and lead forms. Concentrations of different forms of Zn, Cu and Pb were determined to be in the following order: NH4OAc < EDTA < HCl. Heavy metal content in exchangeable form was higher in chestnut soil than in chernozem. Applied heavy metals significantly increased the amounts of all soil forms, especially for Zn. Availability of Zn, Cu and Pb to plants depended on the soil type, decreasing from chestnut soil to chernozem. The barley corn and straw were polluted with heavy metals only when maximum doses of these metals were brought into soils.
