Q. With reference to various fertilizers used in agriculture, consider the following pairs:
| Fertilizer |
Primary Nutrient Supplied |
| 1. Urea |
Nitrogen |
| 2. Muriate of Potash (MOP) |
Phosphorus |
| 3. Diammonium Phosphate (DAP) |
Both Nitrogen and Phosphorus |
| 4. Single Super Phosphate (SSP) |
Sulfur |
Which of the pairs given above are correctly matched?
Answer:
Only three pairs
Notes:
- Urea:
- Correct. Urea is a nitrogen-rich fertilizer, widely used in agriculture for boosting crop growth.
- Muriate of Potash (MOP):
- Incorrect. MOP provides potassium, not phosphorus, and is essential for improving crop quality and stress tolerance.
- Diammonium Phosphate (DAP):
- Correct. DAP provides both nitrogen and phosphorus, making it a balanced fertilizer for many crops.
- Single Super Phosphate (SSP):
- Correct. SSP is a phosphorus-based fertilizer that also provides sulfur, which is beneficial for oilseed crops.
Thus, Only three pairs are correct
