Crop residues are the leftover plant materials that remain in the field after harvesting crops like wheat, corn, or rice. These residues include stalks, leaves, and husks, which can vary in quantity and type depending on the crop grown. Farmers often manage crop residues by incorporating them into the soil, using them as animal feed, or leaving them on the surface to improve soil health. This practice helps prevent soil erosion, enhances moisture retention, and contributes to nutrient cycling, ultimately supporting sustainable agriculture.
