Phosphate rocks are majorly produced only from two States in India, namely Rajasthan and Madhya Pradesh. Rock phosphate is the key raw material for DAP and NPK fertilizers. Currently, India is 90% dependent on imports for this raw material. Most of the phosphate rock mined throughout the world is used to produce phosphate fertilizer.
