Burning destroys micro-organisms which are essential for the formation of humus which binds soil particles together. It destroys vegetable matter that protects the soil against erosion hence less protection. Burning destroys the nitrogen fixing bacteria making the soil less fertile and therefore few plants and less protection of the soil. Burning loosens the soil making it susceptible to erosion or leaching which drains away soluble nutrients.
