The burning of crop residues not only causes environmental pollution, but also lowers the fertility of the soil. Farmers should never burn the crop residues. They have to mix those in soil by deep plowing because they maintain the moisture level in the soil as well as enhance the soil fertility. In this way the input of crop reduces and farmers can save their money by utilizing natural sources of nutrients and lesser application of synthetic fertilizers.
