The government has also approved to reduce sales tax on rock phosphate (part of Potassic fertilizer) from 17 to 10 percent.

Lai have studied fluid inclusions in quartz as well as the oxygen isotopic signature of the quartz from samples associated with early potassic alteration, synmineralization sericite-chlorite alteration, and postmineralization from the Haisugou porphyry Mo deposit, northern Xilamulun district, northeastern China.
Similarly, to promote balanced use of fertilizers, India is giving 70% subsidy on urea, 50% on phosphate fertilizers and 50% on potassic fertilizers.
Poor education and lack of awareness about the balanced fertilization is one of reasons for low potassic fertilizers use among growers.
In addition, there are 21 grades of phosphatic and potassic fertilisers with different subsidy rates.
Similarly, economic subsidy on phosphatic fertilisers is obtained by multiplying the difference between farmgate cost of imported P and its domestic price, with the consumption of P and finally, economic subsidy on potassic fertilisers is derived by multiplying the difference between farmgate cost of imported K and its domestic price, with the consumption of K.
