Why is contour ploughing practised as a primary soil conservation method on hilly terrains?
To reduce water runoff on slopes
Contour ploughing involves ploughing along the natural contour lines of a slope rather than up and down the hillside.
These contour furrows act as small barriers that slow down water flowing downhill, reducing runoff velocity and allowing more water to soak into the soil, which in turn reduces soil erosion.
The method does not increase sand content, remove topsoil, or restrict plant growth — those outcomes would work against soil conservation goals, not support them.
