Question

Suggest any three measures to control soil erosion in the hilly areas.

Answer 1

In hilly areas, soil erosion can be controlled by: 

1) Ploughing across elevation contour lines. The contour lines break water run offs during heavy rainfall, impeding soil erosion.

2) Practicing terrace farming: This is where graduated steps of land are made on the slope to control soil erosion.

3) Planting strips of grass: Grass on the slopes acts as water and wind breaker, therefore limiting the process of erosion.

Answer 2

The measures to control soil erosion in the hilly areas are:-

(a) Terrace farming- On hilly slopes, terraces act as bunds and prevent soil erosion from being washed away by running water.

(b) Contour Ploughing- Ploughing along contours on a slope prevents soil erosion being washed away by rainwater or by surface run off. Contours act like bunds. Terraces are levelled into step-like small fields with even slopes.

(c) Planting Trees- The trees are planted along the edges of the fields, the waste land and on steep slopes to prevent soil erosion as well as to enhance the capacity of the soil to retain water.
