Rock phosphate is the source from which dicalcium phosphate can be manufactured. It finds applicability as a fertilizer. The phosphours pentoxide content ranges around 41-42% in the dihydrate form. The trade mark for a dentrifice grade dicalcium phosphate dihydrate is captioned as "Dicalcium phosphate victor". It is CaHPO4.2H2O plus additive. FCC grade, Which is used as polishing agent in dentrifices. In the shallow, medium and deep-black soils having the carbonate content from 3 to 6 %, the available phosphorous was highest at 60 days when superphosphate was applied, whereas in the alluvial soil containing 1% carbonate , the highest available phosphorous was observed at 60 days when the fertilizer applied was dicalcium phosphate. Dicalcium phosphate proved as effective as superphosphate on alluvial,coastal alluvial, red and laterite soils, but was inferior on medium-black and deltaic saline soils. Non granulated dicalcium phosphate appears to be an acceptable phosphate source for rice on soil other than medium black and deltaic saline. for up land cereals the limited avilable data indicate that some water soluble phosphate is necessary along with dicalcium phosphate. For grain legumes, however, diacalcium phosphate does not seem to be a good source on alluvial, medium-black and mixed red and black soils. It may be mentioned that superphosphate supplied more calcium and additionally sulphur, which could be critical for grain lequmes in some soils. the basic raw material for this product being rock phosphate. It is found as a geological deposit on a large scale in some countiers, like the USA, the USSR, Australia Morocco, Jordon. Tunisa, Egypt,Israel and Peru. Although the first phosphate fertilizer plant in India went into production in 1906, an earnest search for deposits of rock phosphate within the country was made only during the last decade, the richest deposits being discoverd in Udaipur (Rajasthan) in march 1966. phosphatic rocks are now reported to occurs in Andhra pradesh, Assam, Bihar, Himanchal Pradesh, Jammu and Kashmir, orissa, Rajasthan, Tamilnadu and utter pradesh (Fai ,New Delhi, 1972s).The deposit in Andhra Pradesh (Kasipatnam) are in the form of pegmatite veins, which contain apatita, magnetite and vrmiculate ,and the Geological survey of India estimates the deposit to be around 170000 tonnes. In Assam (Garu Hills) and Tamilnadu (Tiruchirapalli) phosphate deposit occur as nodules in calcareous shales or cretaceous beds, and in south arcot (Tamilnadu) and Pondicherry these occur as phosphateised molluscan shells. In Uttar pradesh ,Dehradun and Tehri , generally known as Mussoride deposit and in Himanchal pradesh (Mahasu,Daral and saloni)the deposit are phosphoric (the manu mineral being collophane), which may be granular, nodular, lenticular, platy or pelletal. the estimated reserves in Uttar pradesh are about 17 million tonnes. The apatito reserves in Bihar (singhbhum) are estimated to be 1 million tonnes. In Rajasthan(Udaipure and Jasialmer) the total exploitable reserves are estimated to be over 100 million tonnes, of which 40% are high grade spatite.
