Which of the following is an agronomic measure of erosion control?

Contour bunding is an agronomic measure of erosion control. In contour bunding, bunds or barriers are constructed along the contours of the land. These bunds help to slow down the flow of water, reducing its erosive force and preventing soil erosion. Contour bunding is particularly effective on sloping lands, where water runoff can lead to significant soil erosion. This method helps to retain water on the land, allowing it to percolate into the soil and reducing the risk of erosion. It is a sustainable agricultural practice to conserve soil and water resources.
