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.
