Alpine and subalpine wetland soil physicochemical characteristics, summer 2020.

To understand patterns in soil biogeochemistry of wetlands at Niwot
Ridge, samples were collected and analyzed for a series of
physicochemical characteristics during 2020-2021. Samples were
collected from 8 wetland sites lying at different elevations from
the Saddle into the subalpine. At each site, samples were collected
at 4 depth intervals within 5 sampling nodes along transects from
the dry edge to saturated center of each system. These soils were
analyzed for a suite of physicochemical characteristics, including
soil moisture, bulk density, extractable nitrate and ammonium, loss
on ignition as a proxy for organic carbon content, pH, total carbon
and nitrogen, and adsorbed sulfate. Data will be used to inform
future studies on biogeochemistry patterns and processes in alpine
wetlands and across the Niwot landscape.
