The purpose of this work was to investigate the effects of Cr (III) and Cr (VI) compounds on the activity of acid and alkaline phosphatases in a Mollic gleysol and in Haplic Phaeozem soil samples. It was found that phosphatase activity in the soil decreases with increasing concentrations of Cr (III) in the range 2-20 g t-1. In the case of Cr (VI) an immediate reduction of both acid as alkaline phosphatase activity in relation to the control sample was also observed. Moreover, phosphatase activity has a tendency to diminish the deeper it is found in the soil profile. Soil phosphatase activity is also stimulated by the presence of organic matter.
