Crop residue management: Innovative solutions can douse farm fires -Manjit S Kang

-The Tribune

It must be recognised that a practice that has been going on for over 50 years cannot be stopped at once. Farmers need economically viable solutions. Farmers should have the choice to adopt a solution that best suits them. A sustainable agricultural system is one that produces abundant food without depleting the earth’s resources and without polluting the environment. Thus, it is best if crop stubble is incorporated into the soil. This would enhance soil health and curtail air pollution.

The problem of burning of crop residue (stubble) following combine harvesting of paddy in Punjab and Haryana has been around for more than 50 years. The main causes of stubble burning are the narrow window for sowing wheat after harvesting paddy; labour shortage; much stubble left behind by the combines; and the high cost of removing/transporting stubble.

As estimated by the International Rice Research Institute, each kg of milled rice generates 0.7 to 1.4 kg of rice straw, depending upon the variety of rice, cutting height, and moisture content at the time of harvesting.
