[1] In recent decades, the RockyMountainWest has been one of the fastest growing regions in the United States. Headwater streams in mountain environments may be particularly susceptible to nitrogen enrichment from residential and resort development. We utilized stream water chemistry from six synoptic sampling campaigns combined with land use/land cover (LULC) and terrain analysis in geostatist...

Topography affects soil hydrological, pedological, and biochemical processes may influence nitrous oxide (N2O) emissions into the atmosphere. While N2O from agricultural fields are mainly measured at plot scale on flat topography, intrafield topographical crop growth variability alter might impact emissions. The objective of this study was to examine variations period dependent field scale. A e...
