A new method to measure nitrous oxide soil gas fluxes using chambers in combination with a N2O sorbent is presented. The standard GRACEnet protocols method requires multiple grab samples (typically 25mL e/a) obtained throughout chamber deployment (i.e., 0, 15, and 30 min) and linear and non-linear options to process the raw concentrations, based on goodness of fit tests. The new method uses a single sorbent-stabilized large volume (400 mL) gas sample obtained at the end of each chamber deployment (30 min) and assumes a linear concentration increase. Both methods estimate the initial (time 0) gas flux into the chamber using concentration changes and deployment time. This report presents a side-by-side field test in experimental plots. Samples were independently analyzed by gas chromatography and thermal desorption/gas chromatography for the standard and new method, respectively. Gas concentrations measured by both methods at the end of the chamber deployment and calculated soil gas fluxes were in close agreement (R2 =0.92 and R2 =0.91, respectively). Additionally, four-100 mL samples taken from multiple chambers at the end of the deployment were pooled into a single cartridge to explore the sorbent potential to further reduce the number of samples. Pooled sample results from four locations correlated well with average standard chamber deployments (R2 =0.92 and R2 =0.95 for N2O concentrations and soil gas fluxes, respectively). These results suggest sorbent-based sampling yields soil gas flux data of similar quality to grab sampling methods, and potential advantages of more stable and reduced number of samples.
