Question:
Soil preparation method suitable for the sloping ground is ______________.
Soil preparation method suitable for the sloping ground is ______________.
Show Hint
Slope = Contour based preparation. "Ridge ditch" and "Trenches" are always the preferred answers for hilly terrain afforestation.
Updated On: Aug 20, 2026
- Ordinary pit
- Saucer pit
- Mound
- Ridge ditch
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
Planting on slopes requires methods that prevent soil erosion and conserve moisture by catching runoff water.
Step 2: Detailed Explanation:
• Ridge ditch (or Gradoni) involves digging continuous or staggered trenches along the contour lines of a hill.
• The excavated soil is piled on the downhill side of the trench to form a ridge. Plants are usually put in the trench or on the ridge.
• This method is highly effective on slopes as it breaks the flow of water, catching both soil and moisture that would otherwise be lost to runoff.
• Mounds (C) are used in waterlogged/swampy areas, and ordinary pits (A) are standard for flat land.
Step 3: Final Answer:
The suitable method is the Ridge ditch.
