Methods
of soil conservation:
(i) Contour ploughing: Ploughing along the contour lines
can check the flow of water down the slopes. It is called contour ploughing. It
can be practiced on the hills.
(ii)
Terrace cultivation: Steps can be cut out on the slopes making terraces. It restricts
soil erosion. It is practiced in western and central Himalayas.
(iii)
Strip cropping: Large fields can be divided into strips. Strips of grass are left
to grow between the crops. This breaks up the force of wind. This method is
called strip cropping.
(iv)
Planting of shelter belts: Planting lines of trees to create shelter also
checks the soil erosion. Rows of such trees are called Shelter Belts. These
shelter belts have contributed significantly to the stabilization of sand dunes
