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...

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...
