Název v původním jazyce

Effect of soil sample treatment on an evaluation of trace element (Cu, Fe, Mn, Zn) mobility in soils

Popis výsledku v původním jazyce

The extractability of Cu, Fe, Mn, and Zn with various extracting agents as well as the effect of sample pretreatment (drying, freezing of the soil sample) were evaluated at eight soil samples differing in their physicochemical parameters. The extractability of elements decreased in order Zn > Cu > Mn > Fe. In the case of mild extraction procedures (0.01 mol.l-1 CaCl2, water) the released portions of elements were low and affected significantly by differing physicochemical parameters of individual soilsand also in behavior of individual elements. Two methods of soil solution collection were tested: i) centrifugation of saturated soil and ii) the application of suction cups. Slightly higher Fe and Zn concentrations were obtained by centrifugation methodwhereas Cu and Mn concentrations were lower. However, fairly good correlations between these sampling methods were calculated for Cu (r=0.74), Mn (r=0.94), and Zn (r=0.57).
