Jhamarkotra, near Udaipur, is the leading Indian source of which mineral used in fertilisers?
- A.Rock phosphate
- B.Potash
- C.Sulphur
- D.Nitre
Correct answer
Explanation
The correct answer is A, rock phosphate. Jhamarkotra is the largest rock phosphate deposit worked in India and supplies the raw material for phosphatic fertiliser, which is why the country's dependence on imported phosphate is reduced by it; the mine is run by Rajasthan State Mines and Minerals Limited. Option B is wrong because India has almost no mined potash and imports nearly all of it, though potash bearing rocks have been found in Rajasthan's Nagaur-Ganganagar belt. Option C is wrong because sulphur for fertiliser comes mostly as a by-product of petroleum refining. Option D is wrong because nitre, or saltpetre, is a surface deposit of little present importance. Add the related pair: gypsum from Nagaur is also used for fertiliser and for cement, and Rajasthan leads the country in gypsum as well. Udaipur district is therefore asked twice over, for rock phosphate at Jhamarkotra and for zinc at Zawar.
