Utilization of Crop Residues at the Farmer’s Level in Andhra Pradesh
- Essential Usage for Livestock and Fertilizer
- Residues of Arhar, Groundnut, Rice, and Maize are extensively used as cattle feed.
- Residues from Dry Chili, Groundnut, and oilseeds are predominantly used for composting (manure preparation).
- Fuel Usage for Domestic Needs
Crop residues such as Arhar, Cotton, Sunflower, and Wheat are utilized as fuel for domestic cooking. - Field Preparation through Residue Burning
Stubbles from Arhar, Cotton, Sunflower, Sugarcane, and Rice are often burned openly to prepare fields for the next crop cycle. - Special Usage in Sustainable Farming
- Some farmers practice mulching, where crop residue is used to suppress weeds and reduce water loss through evaporation.
- Zero Budget Natural Farming (ZBNF) is practiced by avoiding chemical fertilizers and utilizing crop residues effectively.
- Commercial Applications
Farmers earn revenue by selling crop residues to briquetting or biomass plants, providing an economic value for agricultural waste.
