Crop rotation helps maintain soil fertility and structure by varying the types of crops grown. Sand fences are used to control sand dune movement and prevent soil erosion in sandy areas, which is relevant in arid and coastal regions of India. Terracing is a crucial technique for reducing soil erosion on slopes, common in hilly and mountainous regions of India. Windbreaks, typically rows of trees or shrubs, are effective in reducing wind erosion and protecting cultivated land.
