Explain how trees help in the conservation of the soil.
- Leaves & branches reduce the force of rain drops which would otherwise loosen
and remove soil particles
- Rate of infiltration of rain water into the soil is increased by vegetation cover thus reducing surface run off
- Tree roots which penetrate the soil help to carry surface moisture into the ground. This allows the moisture to gradually percolate deeply
- Tree roots bind the soil particles together and therefore the soil can not be easily carried away
- Trees break the force of the wind at the ground and reduces the transportation of soil by wind
