Abstract

Plant nutrient release from soil minerals is reported to be speeded at lower soil pH, which is also governed by the acidifying effect of vegetation roots. This research was to investigate the effects of several tropical weeds on the available K in two tropical soils with distinct properties. Five potential weeds including Asystacia gangetica, Arachis pintoi, Widelia sp., Paspalum conjugatum and Pennisetum purpureum were grown in the soil samples contained in polybags. The soil available K was depleted by weeds except in soils planted with A. pintoi as indicated by the positive values of the change in the available K after two monthss growing period, suggesting that A. Pintoi root was more effective than the other four weeds in enhancing the soil available K. The effectiveness of weeds in enhancing the soil available K were: A. Pintoi > A. gangetica > Widelia sp. > P. conjugatum > P. purpureum.
