Question

A farmer adopts terrace farming in a hilly region to grow crops like maize and wheat. He notices that the soil erosion has significantly reduced, and the crops yield better results. What is the primary reason for reduced soil erosion in terrace farming?

Options

• Increased water flow

• Controlled water movement across steps

• Use of chemical fertilizers

• Absence of vegetation cover

Answer 1

Controlled water movement across steps

Explanation:

Terrace farming involves shaping the land into steps, which slows the flow of water and prevents it from washing away soil. This controlled water movement decreases soil erosion and increases crop yields in hilly regions.
