Answer» The problems of soil erosion is very serious. To check it, related natural factors as well biological factors also must be controlled: 1. In flooding areas, by making anicuts and ridges in the field, the flow of water can be controlled. 2. Afforestation should be promoted, while insensible cutting of forests must be stopped. 3. Overgrazing also must be checked. 4. In the dry regions, to reduce the intensity of wind flow, strip cultivation must be practiced. 5. Applying a layer of mulch to the top soil allows the soil to slowly soak up water, as it protects against rain impact and restores pH level, helping to prevent erosion. 6. To avoid soil erosion, terrace farming, growing cover crops, using green manure instead of fertilizers and pesticides, crops cycle, etc. must be practiced. |
