Single Super Phosphate (SSP) Fertilizer industry is the pioneering fertilizer industry in the country and playing an important role in Indian Economy which is based on Agro Productivity. First SSP plant was established by EID Parry during 1906. Manufacturing of SSP is based on perhaps the simplest chemical reaction amongst chemical fertilizer industry. The main raw materials required are rock phosphate and sulphuric acid. SSP is a straight phosphatic multi-nutrient fertilizer which contains 16% water soluble P2O5, 12% sulphur, 21% calcium and some other essential micro nutrients in small proportions. SSP, which is a poor farmer’s fertilizer (price-wise), is an option to optimise the use of phosphatic fertilizers. It also helps to treat sulphur deficiency in soils (40% Indian soil sulphur deficient) as well for further enhancement of yields at the least cost. In various crops, which require more of sulphur and phosphate like oilseeds, pulses, sugarcane, fruits and vegetables, tea etc, SSP is an essential fertilizer.
