Methane and nitrous oxide emissions from rice paddy fields
Recent field studies in rice paddy fields in Japan and China have shown that N2O is emitted to the atmosphere not only after the application of nitrogen fertilisers under flooded conditions but also in a period from the final drainage to submergence in the following rice-growing season through nitrification or denitrification. Those results clearly indicate that CH4 and N2O emissions in rice pa...
متن کاملEstimation of methane and nitrous oxide emissions from Indian livestock.
Greenhouse gas (GHG; methane and nitrous oxide) emissions from enteric fermentation and manure management of Indian livestock were estimated from the last two Indian livestock census datasets (2003 and 2007) using IPCC Tier 2 (2006) guidelines. The total annual GHG emissions from Indian livestock increased in 2007 compared to the year 2003 with an annual growth rate of 1.52% over this period. T...
متن کاملMitigation of Nitrous Oxide and Methane Emissions from Rice-wheat System of the Indo- Gangetic Plain
Mitigation of methane (CH4) and nitrous oxide (N2O) emission from soil is important to reduce the global warming. Efficacy of six nitrification inhibitors i.e. neem cake, thiosulphate, coated calcium carbide, neem oil, hydroquinone and dicyandiamide (DCD) in mitigating N2O and CH4 emissions from fertilized soil in rice-wheat system, which occupies 13.5 million ha of the most productive lands in...
متن کاملTechnical options for the mitigation of direct methane and nitrous oxide emissions from livestock: a review.
Although livestock production accounts for a sizeable share of global greenhouse gas emissions, numerous technical options have been identified to mitigate these emissions. In this review, a subset of these options, which have proven to be effective, are discussed. These include measures to reduce CH4 emissions from enteric fermentation by ruminants, the largest single emission source from the ...
