The study, titled "
Potassic, high-silica Hadean crust," was published June 4 in the (http://www.pnas.org/content/early/2018/05/30/1720880115) journal PNAS.
The government has also approved to reduce sales tax on rock phosphate (part of
Potassic fertilizer) from 17 to 10 percent.
The outlay on phosphatic and
potassic fertilisers under the Nutrient Based Subsidy Scheme has been increased to Rs25,090.35 crore in the next fiscal, up from Rs22,251.8 crore in the current year.
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.
7b) over
potassic formations within the concession are likely to be characterized with highly leached soils.
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.
Petrogenesis of Cenozoic
potassic volcanic rocks in Nangqian Basin.
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.
