Question

Write a note on a mechanical method for soil conservation.

Answer 1

Terrace farming is a mechanical method of soil conservation used on steep slopes. It involves cutting the slope into a series of level steps or benches with bunds of earth or stone; each terrace traps rainwater, reduces runoff velocity and prevents topsoil erosion. Terraces increase water infiltration and moisture retention, make steep land cultivable and lower landslide risk. Construction requires labour and initial cost, and terraces need maintenance. Terrace farming is widely practised in hilly regions to conserve fertile soil and support stable agriculture.
