Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Sub-surface drainage can be established without laying pipes in heavy clay soils.
Step 2: Meaning
This process involves creating unlined underground channels that act as "pipes" for water to flow through.
Step 3: Analysis
A mole plough has a torpedo-shaped "bullet" at the end of a long shank. As it is pulled through the soil, it leaves behind a smooth, circular hole (a mole drain) that stays open in stable clay soils.
Step 4: Conclusion
The mole plough is used for this in-situ drainage method.
Final Answer: (D)
