Methane Efflux

Abstract Methane emission from a wetland was measured with the eddy covariance system. The location of the system allowed observation of methane efflux from areas that were covered by different vegetation types. The data presented in this paper were collected in the period between the13th of June and the 31st of August 2012. During the warmest months of the summer, there was no strong correlation between methane emissions and either the water table depth or peat temperature. The presence of reed and cattail contributed to a pronounced diurnal pattern of the flux and lower methane emission, while areas covered by sedges emitted higher amounts more with no clear diurnal pattern.

<p>Rice production contributes roughly 11% of global CH4 anthropogenic emissions while producing food for over 3 billion people. The alternate wetting and drying (AWD) irrigation practice for rice has the potential to conserve water while reducing CH<sub>4</sub> emissions through the deliberate, periodic introduction of aerobic soil conditions. Our work in the US Mid-South rice production region has demonstrated, using the eddy covariance method on adjacent fields, that AWD can reduce field CH<sub>4</sub> emissions by about 66% without impacting yield. In any strategy, CO<sub>2</sub> and N<sub>2</sub>O emissions should also be monitored to take advantage of the high carbon sequestration potential of rice and low potential N<sub>2</sub>O emissions. Careful water and fertilizer management can theoretically keep N<sub>2</sub>O emissions low. All three gases should be managed together, while sustaining or improving harvest yield, to create a sustainable rice production system.</p><p> </p><p>We now present 5 years of closed chamber measurements of N<sub>2</sub>O and CH<sub>4</sub> and compare them to the eddy covariance measurements of CH<sub>4</sub> and CO<sub>2</sub> to derive a more thorough perspective on the net greenhouse gas (GHG) emissions or global warming potential basis of rice production from the highly productive, mechanized, humid, US Mid-South. Global warming potential of GHG emissions from rice systems was dominated by CH<sub>4</sub> emissions (74 to 100%), hence mitigating efforts need to focus on CH<sub>4</sub> emissions. Greater reduction of CH<sub>4</sub> emissions can be achieved by proper AWD management practice combined with adequate N fertilization. We end with a comment on the upcoming challenge of how to sequester CO<sub>2</sub> uptake as soil organic matter via litter incorporation without increasing CH<sub>4</sub> emissions. </p>
