Answer Details
The practice that is aimed at soil conservation is asked. Therefore, we need to identify the option that is not aimed at soil conservation. The option that is not aimed at soil conservation is bush clearing. Bush clearing involves the removal of natural vegetation cover from the soil surface, which exposes the soil to erosion by wind and water. On the other hand, the other options - contour ridging, application of manures, strip cropping, and crop rotation - are all aimed at soil conservation. Contour ridging involves creating ridges along the contours of a hill, which slows down the flow of water and reduces soil erosion. Application of manures helps to improve soil fertility and structure, which helps to prevent soil erosion. Strip cropping involves planting crops in alternating strips, which reduces soil erosion by wind and water. Crop rotation helps to maintain soil fertility and reduce soil erosion by alternating crops that require different nutrients and have different root systems.
