| Abstract/Contents: | "Insight into the temporal and spatial variability of nitrous oxide (NāO) fluxes from soils is required to set up efficient sampling protocols of NāO fluxes and to set up strategies to reduce NāO fluxes. The aim of the present study was to assess the temporal stability of the spatial pattern of NāO fluxes along a transect (400 m) on a fertelized sloping grassland soil. Geostatistical analyses of flux chamber measurements over 4 d showed a clear spatial dependency of NāO fluxes. The spatial variability of NāO fluxes was much higher than the temporal variability during the 4 d. Despite the decreasing magnitude of the fluxes in time, the spatial pattern persisted during 4 d, that is, fluxes were always highest at the steepest part of the transect. The Ā¹āµN natural abundance (Ī“Ā¹āµN) in soil N was significantly correlated with NāO fluxes, indicating a long-term effect of N loss as NāO on the Ā¹āµN abundance in the soil. It was suggested that topography played a role in the observed spatial patterns of NāO fluxes and ĪĀ¹āµN in soil N. The study showed that despite the persistent spatial pattern of NāO fluxes, flux magnitude may strongly fluctuate in time. Therefore, it is often not possible to combine NāO flux measurements made at different times in order to obtain enough data for geostatistical analysis." |
