dc.description.abstract This investigation was carried out to test the possibility of using two sources of rock phosphate from the Sudan as a phosphorus fertilizer. The two types of rock phosphate examined were collected from Uro and Kurun in Nuba Mountains, Western Sudan. Chemical analysis of rocks indicated that Uro and Kurun rock phosphates contained 20.5 and 25.9% P2O5, respectively. These levels meet the universal requirements to mark the tested rocks as good sources for plant phosphorus. Soluble phosphorus was found to be 0.001 and 0.002% P2O5 for Uro and Kurun, respectively, and the respective citrate - soluble phosphorus was 3.5 and 3.7% P2O5. The heavy metals content of the rocks was also recorded. en_US
