"Smoke, containing Nitrogen oxide and Carbon monoxide, is being inhaled by locals. It affects lungs and eyes," a tuberculosis (TB) expert said, adding elders, children are the worst affected. It can be fatal for asthma patients.
Experts believe that stubble burning is the least-costly option available to the cultivators, while the straw management methods recommended by the state authorities are time consuming. They instead suggested using the residue as fertilizer.
"When the soil is upturned by ploughing the field, the stubble would go inside the earth and would later become compost, an organic fertiliser," they said.
