Crop residue burning impact by Silochana,12th, Adarsh Senior Secondary School

Crop Residue Burning impact (CRB) or the Burning of agricultural biomass residue has been identified as a major health hazard. Burning crop residue causes remarkable pollution problems in the atmosphere and huge nutritional loss and physical health deterioration in the soil. The burning of one tonne of paddy straw releases 3 kg particulate matter 60 kg CO, 2 kg SO2, and 199 kg ash. These gases affect human health due to general degradation in air quality resulting in aggravation of eye and skin diseases, and very fine particles can also cause chronic heart and lung diseases. The composition of nutrients in crop residue is highly rich, one ton of paddy straw contains approximately 2.3 kg P2O5, 5.5 kg N, 25 kg K2O, 1.2 kg S, 50-70% of micro-nutrients absorbed by the rice, and 400 kg of carbon, which is lost due to burning of paddy straw only. India is an annual gross crop residue producer of 371 million tons (mt), of which paddy and wheat residues constitutes 51– 57% and 27–36% respectively. Apart from the loss of nutrients, some of the soil properties like soil temperature, pH, moisture, available phosphorus, and soil organic matter are greatly affected due to burning in the fields.
