Mulching is basically the process of covering the open surface of the ground by a layer of a external material.Some examples are straw,leaves,crop residues,stones or plastic planes.
A rock dam is a rock embankment constructed across a drainageway or other suitable location to create a temporary basin for collecting sediment(I don’t know an example.)
Shelter belt is a wide range o trees, shrubs and grasses planted in rows which go right across the land at right angles to the direction or the prevailing to defect in movement to reduce wind 3. Velocity and to give general protection to cultivated area wind erosion and decreasing effect of hot winds.
