Methods of soil conservation:

(i) Ploughing along the contour lines can decrease the speed o[ water flow down the slopes.

(ii) Step or terrace cultivation on slopes restricts erosion. Western and Central Himalayas have well-developed terrace farming.

(iii) Strip cropping: Here large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind.

(iv) Shelter belt plantation: Tree are planted in rows. These shelter belts have led to the stabilisation of sand dunes and in stabilising the desert in western India.
