Abstract


An incubation study on the dissolution of rock phosphates with soils of different pH, was taken up at Tamil Nadu Agricultural University, Coimbatore. It was concluded from the experiment that the dissolution of Udaipur rock phosphate and Mussorrie rock phosphate were remarkably higher in soils with a pH of 5.8 both at 30 and 60 day of incubation, followed by neutral soil (pH 7.6) and saline soil (pH 8.75).During the initial stage of incubation upto 30 days, the dissolution was found to be higher with Udaipur rock phosphate, whereas at the end of 60 days, Mussoorie rock phosphate recorded higher dissolution.
