Agricultural residues are the leftover materials from farming activities after crops have been harvested. These can include parts of plants such as stalks, leaves, and husks, as well as other organic matter like roots and weeds. They are often left in the field or collected for various uses, including animal feed, compost, or bioenergy production. These residues play an important role in sustainable agriculture by improving soil health and reducing erosion. When returned to the soil, they can enhance nutrient content and support beneficial microorganisms. Proper management of agricultural residues can also help minimize waste and promote environmental sustainability.
