Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Available water holding capacity depends on soil texture, pore size distribution and water retention ability.
Step 1: Understand available water holding capacity.
Available water is the water held between field capacity and permanent wilting point. \[ \text{Available water}=\text{Field capacity}-\text{Permanent wilting point} \]
Step 2: Compare soil textures.
Silt loam generally has high available water holding capacity because it has a good balance of macro and micropores. Clay and clay loam also hold considerable water, while sandy loam holds comparatively less water.
Step 3: Arrange the given soils.
The descending order is: \[ \text{Silt loam}>\text{Clay}>\text{Clay loam}>\text{Fine loam}>\text{Sandy loam} \]
Step 4: Convert into given symbols. \[ B>C>A>D>E \] \[ \therefore \text{Correct Answer is (B)} \]
