Agricultural residue refers to the leftover materials from farming activities, such as crop stalks, leaves, and roots after harvest. These residues can come from various crops, including wheat, corn, and rice. They are often left in the fields or can be collected for other uses. These residues play a significant role in soil health by adding organic matter and nutrients when decomposed. Additionally, they can be used for bioenergy, animal feed, or as raw materials in bioproducts. Proper management of agricultural residue can enhance sustainability in farming practices.
