| Popis: | We report seasonal variation in CH 4 and N 2 O emission rate from solid storage of bovine manure in Delhi as well as emission factors and emission inventory from manure management systems in India. Emission flux observed in the year 2002–2003 was 4.29 ± 1, 4.84 ± 2.44 and 12.92 ± 4.25 mg CH 4 kg −1 dung day −1 , as well as 31.29 ± 4.93, 72.11 ± 16.22 and 6.39 ± 1.76 μg N 2 O kg −1 dung day −1 in winter, summer and rainy seasons, respectively. CH 4 emission factors varied from 0.8 to 3.3 kg hd −1 year −1 for bovines and were lower than IPCC-1996 default values. N 2 O emission factors varied from 3 to 11.7 mg hd −1 year −1 from solid storage of manure. Inventory estimates were found to about 698 ± 27 Gg CH 4 from all manure management systems and 2.3 ± 0.46 tons of N 2 O from solid storage of manure for the year 2000. |
