520			_aPhysical, chemical and mineralogical charecteristics of commercially available Eppawela Rock Phosphate (ERP) was compared with a well known rock phosphate, Gafsa from Tunisia. The phosphate content of Eppawela material was low, around 16;and is two times lesser than Gafsa. Also, the extractable P in ERP was two times lesser than that of Gafsa, indicating its inferiority as a P source. A high amount of silica was present in the Eppawela material as an impurity and it therefore requires to ensure the quality control measures in a systematic way before requires to ensure the quality control measures in a systematic way before it is marketed.
