Three of the following supply phosphate. Which is the odd one out?

  • A.single superphosphate fertiliser
  • B.triple superphosphate fertiliser
  • C.diammonium phosphate fertiliser
  • D.ammonium sulphate fertiliser

Answer: D

Correct answer: ammonium sulphate fertiliser

Ammonium sulphate supplies nitrogen and sulphur and no phosphate at all. The other three are the principal phosphate carriers: single and triple superphosphate from acidulated rock, and diammonium phosphate, which supplies both phosphate and nitrogen and is the most traded phosphate fertiliser.
