Which of these methods will best help to check wind erosion?
Answer Details
Re-afforestation and planting of trees on windbreak is the method that will best help to check wind erosion. This is because the trees act as windbreaks by reducing the velocity of the wind, and hence its erosive power. As a result, the soil is protected from being carried away by the wind. Additionally, the trees also stabilize the soil by increasing its porosity and retaining moisture, which further reduces the susceptibility of the soil to wind erosion. Inter-cropping and contour ploughing, strip cropping and crop rotation, and contour ploughing and manuring are also useful techniques for soil conservation but are not as effective in checking wind erosion as planting of trees on windbreaks.
