अनाज की पराली प्रबंधन के प्रभावी उपाय Wheat and rice are staple food of India so they are grown in large areas. These two crops i.e. rice and wheat, play major role in our economy. After harvesting of these crops they produce a large amount of residue that remains in the field. The farmer burns the residue or this waste material on the farm. When the farmers harvest crop grains by thresher but stubbles remain in the field, for cleaning field they use to burn the stubble or when the gap between the harvesting and showing is less then stubbles are burned.   Burning leads to produce toxic gases that leads to pollute the environment and effect the health that leads to unhealthy all year-round becomes unbreathable during winter, smog, fog, where visibility is low, is due to particulate matter emissions from farm fires in Punjab, Haryana, and Western Uttar Pradesh. This contributes to the   Delhi’s air pollution crisis, and short-term solutions sustain only till the skies clear up. There is no denying that the effects of seasonal paddy stubble burning are severe it causes an estimated loss of 150,000 years of healthy life annually. Underlying stubble burning, however, is a paddy-wheat cropping system with wide-ranging effects on the region. Recently Punjab Chief Secretary Vijay...

फसल अवशेष प्रबंधन की आवश्यकता Burning of crop residues has a bad effect on the number of micro-organisms present in the soil and burning of crop residue destroys all types of beneficial micro-organisms in the most active layer of soil up to 15 cm. Burning crop residues reduces the number of friendly insects like earthworms, spiders. This does not lead to natural control of harmful insects, resulting in the use of costly insecticides. फसल अवशेष प्रबंधन की आवश्यकता भारत में पहले खेती केवल जीविकोपार्जन के लिए किया जाती थी लेकिन धीरे धीरे खेती ने व्यवसाय का रूप ले लिया है। किसान अधिक उपज प्राप्त करने के लिय अंधाधुंध रासायनिक उर्वरक, कीटनाशकों का प्रयोग कर रहा है जिससे मृदा के साथ-साथ पर्यावरण पर भी हानिकारक प्रभाव हो रहा है फसल अवशेष को जलाना भी एक पर्यावरण तथा मृदा प्रदूषण का महत्वपूर्ण कारण है। पिछले कुछ वर्षों में एक समस्या मुख्य रूप से देखी जा रही है कि जहां हार्वेस्टर के द्वारा फसलों की कटाई की जाती है उन क्षेत्रों में खेतों में फसल के तने के अधिकतर भाग खेत में खड़े रह जाते हैं। तथा वहां के किसान खेत में फसल के अवशेषों को आग लगाकर जला देते हैं। खरीफ सीजन में 500 लाख टन फसल अवशेष का उत्पादन होता है। फसल के अवशेषों का सिर्फ...

फसल अवशेष जलाना: कारण, प्रभाव और प्रबंधन Crop Residue Burning (CRB) or 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 to 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 causes chronic heart and lung diseases. The composition of nutrients in crop residue is highly rich, like 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 rice and 400 kg of carbon, which are 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 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. The major impact of crop residue burning are...
