Abstract

The activities of phosphatases in soils have been suggested to be affected by heavy metals but data on the effect of individual metal element, particularly in tropical soils, is scanty. This research evaluated the effect of some heavy metals on the activity of acid phosphatase in tropical and temperate soils. The results showed that the activity of acid phosphatase was significantly reduced either by Pb or by Cd, but not by Cu or Fe. Addition of Cd at 40 mg kg-1 reduced the acid phosphatase activity as much as 44% in Japanese soil and 43% in Indonesian soils: while Pb of the same level decreased the acid phosphatase activity as much as 54% in the Japanese soil and 39% in the Indonesian soil.
