Utilization of Crop Residues at the Farmer’s Level in Karnataka
- Essential Usage for Livestock and Fertilizer
- Crop residues from Bajra, Gram, Groundnut, Jowar, Maize, and Moong are widely used as cattle feed.
- Residues of Arhar, Bajra, Dry Chilies, Bengal Gram, Groundnut, Jowar, Maize, Moong, Onion, and Sunflower are utilized for preparing compost fertilizers.
- Specific Usage in Construction
Arhar residue is often used for thatching roofs and constructing small huts. - Fuel Usage for Domestic Needs
Farmers commonly use stalks of Arhar, Cotton, and Sunflower as fuel for domestic cooking. - Field Preparation through Residue Burning
Burning of Paddy and Wheat stubbles is a common practice to prepare fields quickly for the next crop cycle. - Commercial Applications
Farmers generate income by selling crop residues to briquetting or biomass plants, adding economic value to agricultural waste.
