Fertilizer Salt Index Ordering
The salt index is a measure used to compare the relative salt concentration effect of different fertilizers on soil. A higher salt index signifies a greater potential for soil salinization and subsequent plant stress.
Fertilizer Salt Indices Data
Below are the commonly accepted approximate salt index values for the fertilizers mentioned:
| Fertilizer | Letter Code | Approx. Salt Index |
| Ammonium nitrate | D | ~59 |
| Ammonium sulphate | C | ~70 |
| Urea | A | ~75 |
| Potassium nitrate | E | 100 |
| Sodium nitrate | B | ~105 |
Determining Increasing Order
To find the increasing order of salt indices, we arrange the fertilizers from the lowest value to the highest:
- Ammonium nitrate (D) - ~59
- Ammonium sulphate (C) - ~70
- Urea (A) - ~75
- Potassium nitrate (E) - 100
- Sodium nitrate (B) - ~105
The resulting sequence based on standard values is D, C, A, E, B.
Selected Answer Analysis
The question asks for the increasing order. Option B presents the sequence A, D, C, E, B.
This sequence corresponds to:
- A. Urea
- D. Ammonium nitrate
- C. Ammonium sulphate
- E. Potassium nitrate
- B. Sodium nitrate
