| Abstract: | The rate of dissolution of dicalcium phosphate dihydrate (DCP) when incorporated in moist soil was investigated using 32P. The moisture content of the DCP-soil mixture, the surface area of the DCP particles and the temperature of incubation of the system are all directly related to the rate of dissolution of the DCP. These results may be explained using a diffusion model in which phosphate ions diffuse from a water film adjacent to the DCP towards a sink provided by the soil. |
