Zinc migration patterns in the soil-plant systems were studied in the pot experiment as dependent on soil type, as well as metal concentrations. The quantified values of Zn migration were determined with use of fodder beans (Vicia faba L.) as a test culture. Threshold concentrations of Zn were established in the sod-podzolic sandy loam, peat swamp low-lying soils and chernozem leached silty clay loam, which manifest itself in phytotoxicity. It is shown that edaphic factors play an important role in regulating the mobility of Zn in the soil -plant system as physiological characteristics of the plants. The different approaches to rationing of Zn in soils are also presented.
