Greenhouse Gas Fluxes — GLBRC Scale-up Experiment
Data in the KBS GLBRC core database may not be published without written permission of the lead investigator or project director Full terms of use
Fluxes of N2O, CO2, and CH4 from soils of all fields of the GLBRC Scale-up Experiment using static chambers. Fluxes are corrected to the 3-meter air temperature at 10 am on the day chamber gases were sampled.
This datatable is part of the Greenhouse Gas Fluxes—GLBRC Scale-up Experiment dataset.
This dataset contains greenhouse gas (GHG) fluxes of nitrous oxide (N2O), carbon dioxide (CO2), and methane (CH4) from soils of the GLBRC Scale-up Experiment and includes flux data for all fields at Lux Arbor (L1-L3) and Marshall Farms (M1-M4) planted to corn (L1, M1), switchgrass (L2, M3), and restored prairie (L3, M2) in 2010 after a 2009 no-till soybean crop in all fields to convert tilled corn-soybean-wheat rotations (AGR) at Lux Arbor and fields in the Conservation Reserve Program (CRP) at Marshall Farm to no-till bioenergy crops. One field at Marshall Farm (M4) remains as CRP brome grass. GHG fluxes are measured at approximate 2-week intervals during the growing season using static chambers. Soil temperature and moisture at the time of gas sampling are also determined.
