Abstract

                                It may be said without fear of contradiction that the problem of soil erosion started when the first man turned the sod in the garden of Eden and began upsetting the equilibrium established by Nature. We are all aware that the native grass that clothes the Earth's surface and the vegetation that springs up spontaneously are the anti-erosion controls of Nature. The cover or canopy effect of vegetation, the mechanical hindrance to the flow of water by stems and roots, the soil-binding property of the roots of plants and the biological effects brought about by the addition of dead and decaying organic matter year after year; all these contribute towards the control of soil erosion.
