Abstract
This paper mapped the accumulation and availability of zinc and manganese in young wheatgrass plants (Triticum aestivum L.) grown in typical agricultural soil (Calcic Phaenozem) of Western Slovakia. For estimation of zinc and manganese availability the biological, chemical and radiochemical methods with application of 65Zn and 54Mn isotopic dilution and gamma spectrometry were used. Radiochemical and statistical analyses of obtained metal concentrations in plant tissues, soil samples, soil extracts and isotopically exchangeable fractions (E-values) confirmed the significant correlations mainly between wheatgrass concentrations and E-values. Results showed the important role of isotopic dilution methods for quantification of available metal fractions.
