Possible emissions of N2O from plants in coniferous-deciduous mixed forests

Aboveground vertical profiles of N2O concentrations were measured within two natural coniferous-deciduous mixed forests of 1998 and 1999 in Changbal Mountain. Significant high N2O concentrations were found in six profiles out of twelve profiles. The results showed that high concentrations were 3.03%...

Summary:Aboveground vertical profiles of N2O concentrations were measured within two natural coniferous-deciduous mixed forests of 1998 and 1999 in Changbal Mountain. Significant high N2O concentrations were found in six profiles out of twelve profiles. The results showed that high concentrations were 3.03% to 64.9% higher than the “normal concentrations” in these six profiles. Differences between the high concentrations and the “normal concentrations” were statistically significant. The simultaneous occurrence of high concentrations at/nearby the canopy height and normal concentrations at the trunk space height indicated an efflux of N2O from portant source of atmospheric N2O in a forest ecosystem.
