N2O flux and N15 site preference measurements from Ostrom et al. (2021)
This datatable is part of the Greenhouse Gas Fluxes—GLBRC Biofuel Cropping System Experiment dataset.
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.
