The methods of soil conservation in hilly regions are : 

(i) Plowing along the contour lines decreases the speed of water low down the slopes. 

(ii) terrace cultivation on slopes decreases erosion. 

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

(iv) Shelter plantation: here Tree are planted in rows. These shelterbelts have led to the stabilization of sand dunes and in stabilizing the desert in western India.
