Greenhouse Gas Fluxes—GLBRC Biofuel Cropping System Experiment

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.

Tables

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).
