With reference to chemical fertilizers in India, consider the following statements : 1. At present, the retail price of chemical fertilizers is market-driven and not administered by the Government. 2. Ammonia, which is an input of urea, is produced from natural gas. 3. Sulphur, which is a raw material for phosphoric acid fertilizer, is a by-product of oil refineries. Which of the statements given above is/are correct ?

  1. (a) 1 only
  2. (b) 2 and 3 only ✓ UPSC's answer
  3. (c) 2 only
  4. (d) 1, 2 and 3

Why the answer is (b)

• Statement 2 is correct: urea is made by reacting ammonia with CO2, and ammonia in India is produced mainly from natural gas (or imported LNG) by steam reforming.

• Statement 3 is correct: elemental sulphur, recovered as a by-product when refineries desulphurise crude oil, is burnt to make sulphuric acid, which converts rock phosphate into phosphoric acid for DAP/SSP.

• Statement 1 is wrong: urea's retail price is fixed by the Government (statutorily controlled), and P&K fertiliser prices are influenced by nutrient-based subsidy; they are not purely market-driven.

• Hence 2 and 3 only, option (b).

Why the other options are wrong

(a) 1 only
Statement 1 is wrong: urea prices are administered.
(c) 2 only
Statement 3 on refinery sulphur is also correct.
(d) 1, 2 and 3
Statement 1 is wrong.
