GLBRC085:Greenhouse Gas Fluxes—GLBRC Biofuel Cropping System Experiment
This dataset contains greenhouse gas (GHG) fluxes of nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) from soils of the GLBRC Biofuel Cropping System Experiment (BCSE) and includes flux data for all treatments (G1-G10) at both KBS and Arlington sites. GHG fluxes are measured at approximate two-week intervals during the growing season using static chambers. Soil temperature and moisture at the time of gas sampling are also determined.

- GLBRC085-001 Greenhouse Gas Fluxes
Fluxes of N2O, CO2 and CH4 from soils of all BCSE treatments (G1-G10) measured either by extracting gas samples from static gas flux chambers and analysis by gas chromatography/infrared gas analyzer (gc) or since 2018 by recirculating flow from the flux chamber through an integrated cavity output spectroscopy (icos) unit. Fluxes are corrected to the 3- meter air temperature at 10 am on the day chamber gases were sampled.
- GLBRC085-003 Soil Temperature at Greenhouse Gas Sampling
Soil temperature measured at 1 inch below the soil surface during sampling of greenhouse gases from static chambers.
- GLBRC085-005 Soil Moisture at Greenhouse Gas Sampling
Gravimetric soil moisture of surface soil samples (0-25 cm) taken once in each plot during each greenhouse gas sampling campaign.
- GLBRC085-010 N2O fluxes and N15 site preference data from Ostrom et al. 2021
N2O flux and N15 site preference measurements from Ostrom et al. (2021)
- GLBRC085-011 Automated Gas Chamber
- data table under development
- GLBRC085-012 N2O, CO2, and CH4 by ICOS and TGA
- WARNING : in development QC needed. The purpose of this experiment is to study the spatial variablity for 2 of the BCSE treatments. G1 and G5. Six chambers were deployed on each plot of replicate 1 in the BCSE and the trace gases measured using a LGR ICOS (N2O) and a Licor TGA (CO2 and CH4).
