Which is the most suitable fertiliser for paddy ?
Correct answer: B. Ammonium sulphate
- A. CAN
- B. Ammonium sulphate
- C. Ammonium nitrate
- D. Superphosphate
Explanation
Ammonium sulphate is well suited to paddy because it supplies ammonium nitrogen, which is retained effectively in flooded, reducing soil, and also provides sulphur. Nitrate-based fertilisers are more liable to lose nitrogen through denitrification in standing water.
