Trace gas fluxes from the N-deposition experiment
The data is embargoed for QC.
This datatable is part of the Tracegas fluxes in forests and old fields under enhanced nitrogen regimes dataset.
10 m2 plots in the old field and forest ecosystems were fertilized with 2 rates of nitrogen. N2O, CO2 and CH4 measurements were made with a static chamber method
