Sažetak
A pot experiment was set up to investigate the effect of municipal and tannery sewage sludge loads on four soils (acid and calcareous sandy soils as well as acid and calcareous loamy more heavy soils with different basic soil properties) and plants. The examined soil element fractions were: mobilisable: 0.5 M NH4- acetate + 0.02 M EDTA extractable and the mobile: 1 M NH4NO3 extractable. Applied sewage sludge loads were: 0, 5, 10, 20 g sludge D.M. kg/air-dry soil. Number of treatments was: 4 soil x 2 sludge x 4 load level = 32, in 4 replications. The test plant was barley. Our results showed that the relative amount of soluble Cr content in soil does not increase by the amount of sludge loads. Thus the risk of contamination of food chain and groundwater by Cr after sludge application does not increase linearly by the volume of sludge applied. Based on the result of this experiment one can state that Cr accumulates more in the barley straw than in the grain. In function of sludge loads the BCF values for Cr lessened.
