Phosphorus fixing capacity of a volcanic soil on the slope of mount Cameroon

Abstract

The volcanic soils on the slope of mount Cameroon are deficient in available phosphorus (P) resulting in low productivity. Excess P could be a threat to the aquatic environment. There is therefore need to monitor the P-fixing capacity of these soils with depth. The transformation of applied P in soils from different horizons were examined after treatments with different P rates (0, 20, 60 and 180 mg P L -1
