Soil with high mechanical impedance requires
A. Harrow
B. Moulboard plough
C. Cultivator
D. Chisel plough
Answer: Option D
Solution(By Examveda Team)
Soil with high mechanical impedance requires Chisel Plough. A chisel plough is a common tool to get deep tillage with limited soil disruption. It helps to loosen and aerate the soil while leaving crop residue at top of the soil.Mechanical impedance is ubiquitous within the root environment. Penetration resistances of 0.5 - 1.0 MPa and greater are experienced in soil and reduce root elongation rates.
