Note 1 to entry: GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O),  37 % percent of produced methane gases, a gas that has 22 times more global warming potential than carbon dioxide. ☹ 65 % of produced nitrous oxide comes  The most important anthropogenic GHGs are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

(a) CFC > N2O > CO2 > CH4 (b) CFC > CO2 > N2O > > CH4 > CO2 (d) CFC > CH4 > N2O > CO2 2014-03-14 As metrics for comparison, we have used the GWP contributions of CH4 and N2O for the different straw management practices over two cropping seasons in the field. On an annual basis, SRt had the highest total GWP (8023 kg CO2eq ha−1). SB entailed a GWP of 4913 kg CO2eq ha−1 that was almost identical to the GWP of PSRm (4531 kg CO2eq ha−1). How does burning of rice straw affect CH4 and N2O emissions?

For example, methane (CH4) is often given a GWP of x21 and nitrous oxide (N2O) a GWP of x310. So if each tonne of these gases is multiplied by its GWP and added to the CO2 gas total, the result will be total CO2e. Please note that the numbers may not add up precisely …

Therefore, direct N 2 O emissions dominated the GWP of the saline–alkaline systems in this study. Adviento-Borbe et al. (2007) pointed out that soil N 2 O emissions were a major contributor to the GWP in eastern Nebraska, USA. The total GWP of CH4 and N2O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively.

warming potential (GWP) 270 times that of CO 2 (Neubauer and Megonigal 2015) and are pre-dicted to be responsible for approximately 5% of total global warming (IPCC 2001). Further, N 2O is an significant ozone-depleting substance and is predicted to be the single most important ozone-depleting emission during the 21st cen-tury (Ravishankara et

Compared with the treatments without biochar addition, the annual GWP of N2O and CH4 and vegetable yield wer … [21] In terms of global warming potential, national level CO 2 uptake served to mitigate GWP at a rate of 657.5 ± 374.9 Tg CO 2 eq yr −1, while national CH 4 and N 2 O emissions proved to be enhancers of GWP at rates of 275.1 ± 48.3 Tg CO 2 eq yr −1 and 285.5 ± 131.0 Tg CO 2 eq yr −1 at a 100 year time horizon. In this study, a meta-analysis was conducted to investigate the effect of mid-season drainage on GWP and the factors that control the response of GWP to mid-season drainage. Results showed that mid-season drainage decreased CH4 emission by 52% while increased N2O emission by 242%. The development of a process-oriented global biogeochemical model for soil N2O emissions (with a 2.5 degree x 2.5 degree spatial resolution) and a more empirically based global model for wetland CH4 emissions (1 degree x 1 degree resolution) are described.
