The bare treatment with recently incorporated plant debris, decreased the specific activity of bglucosidase
compared to the mature plant treatment, but was not significantly different in specific activity of either bxylosidase
or cellobiohydrolase. The specific activities of phenol oxidase and peroxidase were lower in the forest
than in plantations and were largely unaffected by the incorporation of plant material in the bare treatment. The specific
activity of phosphatase increased in the plantation soils compared to the forest and the specific activity of sulphatase
did not differ among any of the treatments.
