Abstract

This research was to evaluate changes in the activity of acid phosphatase in zeolite-treated paddy fields with different planting systems. Soil samples were collected from field plots treated with decreasing portion of NPK, that was substituted with zeolite, and cropped to paddy plants with different planting systems. The activity of acid phosphatase decreased with the increase in zeolite portion, except that the 25% NPK and 75% zeolite combination caused the higher phosphatase activity compared to those of lower zeolite portions. The decreasing trend in acid phosphatase by increasing portion of zeolite was consistently shown, regardless of the planting systems. However, the activity of acid phosphatase in the replanting system tended to be higher than those in the direct seeded system.
