Bogner, J.E., R.L. Sass, and B.P. Walter, 2000: Model comparison of methane oxidation across a management gradient: Wetlands, rice production systems, and landfill. Glob. Biogeochem. Cycles, 14, 1021-1033, doi:10.1029/1999GB001224.

Through model experiments we quantitatively examined fractional methane oxidation and net methane emissions using three model systems which encompass a management gradient from pristine (wetlands) to managed (rice production) to highly energized (landfills). Fractional methane oxidation is rarely determined in situ; thus our goal was to cross-compare modeling results and major drivers to field and laboratory data for this important parameter in both pristine and managed systems. In the models, management factors are typically introduced as combinations of theoretical relationships, empirical functions, or scaling factors which drive net emissions through forcing of water table variations, availability of degradable organic carbon substrates, input and cycling of major nutrients, variability in plant communities, physical properties for gaseous transport, and indigenous capacity of soils for methane oxidation. The net methane emission and fractional oxidation vary by orders of magnitude within and among the three model system, yet each model was quite consistent in its predictive ability. This study lays the groundwork for a more unified, modular approach to modeling methane emissions from soil sources where both natural (climatic and ecological) and anthropogenic factors are important drivers.
