This dataset includes measurements of soil nitrogen pools and fluxes from two vegetation types (forest and herbaceous) and two landscape positions (upper and lower slopes) in the Knowlton Fork sub-catchment of Red Butte Creek watershed. Sites are located near the iUtah Knowlton Fork Climate Station, and measurements were made during June, August, and October of 2015. The dataset includes concentrations of inorganic nitrogen, soil nitrate isotope values, bulk concentrations and stable isotope values of soil organic carbon and nitrogen, concentrations of soil microbial biomass carbon and nitrogen, and nitrate leachate from below the rooting zone. Also included are carbon and nitrogen concentrations and isotope values from leaves.

Name Value
Observed Variables soil ammonium concentrations, soil nitrate concentrations, soil nitrogen, soil carbon, nitrate isotopes, soil nitrogen isotopes, soil carbon isotopes, soil microbial biomass, leaf nitrogen, leaf carbon, leaf nitrogen isotopes, leaf carbon isotopes
Variable Description Various soil nitrogen parameters
Data Collection Method Soils, vegetation, and microbial biomass were sampled at discrete intervals throughout the 2015 growing season. Concentrations and isotope values of carbon and nitrogen in total and inorganic pools were analyzed using standard laboratory and analytical techniques. Please attached document for more details on sample preparation and analysis.
Data Processing Method Samples were processed and analyzed at the University of Utah using a suite of advanced instrumentation. Appropriate internal standards and secondary reference materials were always used in order to ensure precision and accuracy of generated data. Please see attached document for more details on quality control and calibration methods.
