Question

Which of the following soils has the highest water holding capacity?

• A. Sandy soil
• B. Clay soil
• C. Loam soil
• D. Clay loam soil

Hint:

Water holding capacity:
- Clay > Clay loam > Loam > Sandy loam > Sand.
- Clay holds more water due to small pores and high surface area.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of soil water holding capacity.

Step 2: Detailed Explanation:
Clay soil (B) has the highest water holding capacity.
Clay particles have high surface area and micropores that retain water tightly.
Sandy soil (A) has low water holding capacity due to large pores and low surface area.
Loam soil (C) has moderate water holding capacity.
Clay loam (D) has high but less than clay.
Thus, clay soil has the highest water holding capacity.

Step 3: Final Answer:
Thus, clay soil has the highest water holding capacity, which corresponds to option (B).
