फसल उत्पादन में अवशेषों का पुनःचक्रण Residues are the by-products of crops plants and other vegetative products of plants are which are organic in nature and has vital importance for agricultural production. The monotonous use of inorganic fertilizers devoid of balanced NPK and micronutrients has resulted in decreasing soil organic carbon (SOC) and fatigued crop production. Soil organic matter (SOM) mostly obtained from organic residues facilitates the aggregation and structural stability of soils and responsible for air-water relationship for root growth and protection of soil from wind and water erosion. The composting, in-situ incorporation or retention as stubble mulch are the common methods of residue management. Residues in general are C-rich materials but contain sufficient amounts of essential plant nutrients. Therefore, their recycling in crop production is an important means of meeting nutrient requirements of the crop plants. Hence, residue application is useful to enhance crop productivity, soil health and profitability both in irrigated and rainfed ecosystems. Scope of Crop residues recycling Indian agriculture is entering a new phase. With time the growing concerns for sustainable agriculture have shown a positive response with the advance of conservation agriculture and it has come as a new paradigm to achieve goals of sustained agricultural production. The residue recycling is more common in conservation agriculture.About 675 Mt crop...

Harmful effects of burning crop residues and management of crop residues भारत में पहले खेती केवल जीविकोपार्जन के लिए किया जाती थी लेकिन धीरे धीरे खेती ने व्ययसाय 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 जलना भी एक पर्यावरण तथा मृदा प्रदुषण 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। क्या है फसल अवशेष  फसल अवशेष पौधे का वह भाग होता है जो फसल की कटाई और गहाई के बाद खेत में छोड़ दिया जाता है। भूसा, तना, डंठल, पत्ते व छिलके आदि फसल अवशेष कहलाते हैं। सरसों, गेहूं, धान, ग्वार, मूंग, बाजरा, गन्ना व अन्य दूसरी फसलों से काफी मात्रा में फसल अवशेष मिलते हैं। सबसे ज्यादा फसल अवशेष अनाज वाली फसलों में तथा सबसे कम अवशेष दलहनी फसलों से मिलते हैं। खरीफ सीजन में 500 लाख टन फसल अवशेष का उत्पादन होता...

कार्बन ट्रेडिंग पर अंतर्राष्ट्रीय सम्मेलन और वैश्विक पहल Carbon is the common denominator in all polluting gases that cause global warming. Carbon dioxide is the gas most commonly thought of as a greenhouse gas. It is responsible for about half of the atmospheric heat retained by trace gasses. It is produced primarily by burning of fossils fuels and deforestation accompanied by burning and bio-degradation of biomass.  It is estimated that if the CO2 increases in the atmosphere at the present rate and no positive efforts are pursued, the level of CO2 in the atmosphere would go up to 800-1000 ppm by the end of current century. Which may create havoc for all living creatures on earth. The Intergovernmental Panel on Climate Change (IPCC) have predicted that unless emissions of greenhouse gases decrease there will be a temperature increase of between 1.4oC and 5.8oC by 2100. Carbon trading The idea behind carbon trading is quite similar to the trading of securities or commodities in a marketplace. Carbon would be given an economic value, allowing people, companies or nations to trade it. If a nation bought carbon, it would be buying the rights to burn it, and a nation selling carbon would be giving up its rights to burn it.  A market would be created to facilitate the buying...
