Organic phosphorus and phosphatase activity in cocoa soils of Ghana
Organic P and phosphatase activity of soils cropped to cocoa and of adjacent soils under bush fallow were determined. The cocoa cultivated soils generally had lower organic P content than their adjacent uncropped soils. The average phosphatase activities were 449 microgram phenol/g soil, range (198-954), and 526 microgram phenol/g soil, range (279-972), for the cocoa and uncultivated soils respectively. Phosphatase activity correlated significantly with organic C, total N and organic P in the bush samples but not in the cocoa soils. The phosphatase activity assumed to be of microbial origin, decreased substantially with increasing incubation temperature with activity ceasing at 100 centigrade grade. The larger proportion of activity detected was attributed to acid and neutral phosphatases is most of the samples. Alkaline phosphatases were dominant in Okroase soil
