The main advantage of using a chisel plow over a moldboard plow is:
Show Hint
Chisel plowing is a conservation tillage method that minimizes erosion by leaving residues on the surface.
Updated On: Jul 2, 2026
- Complete soil inversion
- Reduced soil erosion
- Enhanced weed control
- Increased fuel consumption
Show Solution
Verified By Collegedunia
The Correct Option is B
Approach Solution - 1
Chisel plows loosen the soil without turning it over completely, preserving crop residues on the surface. This practice reduces soil erosion and maintains soil structure, making it suitable for conservation tillage systems.

Contrast with Moldboard: The question is a direct comparison, so line up what each plow does to the soil surface.
A moldboard plow fully inverts soil, burying residue and leaving bare soil exposed to erosion. A chisel plow only loosens soil WITHOUT inverting it, so crop residue stays on the surface — protecting against erosion.
Complete inversion and enhanced weed control are actually moldboard-plow strengths, and chisel plowing needs LESS fuel (shallower disturbance), not more — ruling out the remaining options.
