                        How can we stop soil degradation?   

Answer:

We can stop soil degradation by following the under-mentioned techniques:

(i) Mulching: It involves the covering of bare ground between the plants with organic matter to retain moisture in the soil.

(ii) Contour Barriers: We can stop soil degradation by building barriers along contours to collect water.

(iii) Rock Dam: It means the piling up of the rocks to prevent gullies and soil loss.

(iv) Terrace Farming: This type of farming must be done on the steep slopes to reduce surface run off and soil erosion.

(v) Intercropping: It means to grow different crops in alternate rows to protect soil from rain-wash.

(vi) Contour Ploughing: It refers to performing ploughing parallel to the contours to form natural barriers to check the soil erosion.

(vii) Shelter Belts: They are mainly done in the coastal and dry regions to check the wind movement in order to prevent soil erosion.
