The soil enzymatic properties are greatly affected by cropping system. This research was to investigate the changes in the activities of some soil enzymes in soils continuously cropped with cassava. Soil samples were collected from a cassava plantation in Gunung Balin, North Lampung, that had been cropped with cassava for the time span ranging from 1 to 10 years. The activities of acid and alkaline phosphatase and --glucosidase were consistently lower in soils cropped with cassava, regardless of the time span of cultivation, compared to that in the original land use system that had not been opened for cassava cultivation. The adjacent soils cropped with corn and long bean showed higher activity of acid phosphatase than did the soils cropped with cassava, but the activities of alkaline phosphatase and -glucosidase in the two groups of land use systems were not different. This observation suggests that land use conversion to cultivated land degrades the soil enzymatic properties regardless of cropping system.
