Abstract
The dissolution of two PR materials, Gafsa (GPR) and Christmas Island A (CIPR), in six acid, Malaysian soils (pH 3.0-5.4) was examined in closed-incubation and open-leaching systems. In the closed-incubation system, dissolution of the reactive GPR was higher (22-71%) than that of the less reactive CIRP (26-42%). In the closed-incubation system the size of the sink for Ca determines the extent of PR dissolution in these high P-sorbing soils. With one exception, the dissolution of both PR materials was larger (56-94%) in the open-leaching system and there was less difference in the extent of dissolution between the two PR materials and among the various soils. Studies of PR dissolution in soils using a closed-incubation system provide information that is less relevant to the field situation than do related studies involving an open-leaching system. -from Authors
