Question

pH value of alkaline soil is

• A. 5.0
• B. less than 4.0
• C. more than 7.0
• D. 6.0

Hint:

Think of soil pH like water: 7 = neutral, below 7 = acidic, above 7 = alkaline.

Answer 1

The Correct Option is C

Step 1: Recall soil reaction basics.
- Acidic soil: pH $<$ 7
- Neutral soil: pH = 7
- Alkaline soil: pH $>$ 7
Step 2: Analyze options.
(A) 5.0 – acidic.
(B) less than 4.0 – strongly acidic.
(C) more than 7.0 – correct for alkaline soils.
(D) 6.0 – slightly acidic.
Step 3: Conclusion.
Hence, alkaline soil has a pH value greater than 7.0.
