What happens when an saline-alkaline soil is reached with water:
Correct answer: D. pH increase & Ec decrease
- A. pH decrease, Ec increase
- B. pH & Ec both increase
- C. None of these
- D. pH increase & Ec decrease
Explanation
Leaching a saline-alkaline soil removes soluble salts, so its electrical conductivity decreases; removal of soluble salts also allows exchangeable sodium effects to become more pronounced, often raising pH. Thus pH increases while EC decreases.
