Preventive measures are based on the principle of soil management that minimizes the raindrop impacts enhances and maintains favorable soil structure, minimizes surface crust, favors a high infiltration rate, and reduces runoff rate and amount. The most commonly recommended soil management techniques for erosion prevention are cover crops (Plate 16), residue mulch (Plate 17), and conservation tillage (Plate 18). Relevant crop management techniques for erosion control involve those that provide continuous ground cover (e.g., mixed cropping (Plate 19), strip cropping (Plate 20)), and improved systems of crop management (e.g., new varieties, good-quality seed, early planting, balanced fertilizer use, pest control measures, and other agronomic techniques of good farming that ensure optimum crop stand, vigorous growth, and high yields).
