Abstract

                                The importance of fertiliser production in the economy of our country with agriculture as the main industry cannot be over-emphasised. Also, self sufficiency in this direction presents itself as a mirage, demand far out-stretching supply. Among many factors, the formidable are the scarcity of raw materials like sulphur and quality rock phosphate at home. Prospects of foreign import are indeed dull involving foreign exchange. It will therefore, certainly be an attractive proposition to hit upon a process to dispense with sulphur altogether and make use of indigenous inferior raw materials like phosphate deposits of Trichy and Singhbhum and also Schoenite, a by-product of salt industry. Success in this direction for the production of phosphatic fertilisers will be hailed as a significant revolution.
