Choi, R.T., Reed, S.C., and Tucker, C.L., 2021, CO2 concentrations and microbial biomass data derived from incubation experiments on soils collected at Arches National Park in 2017 and 2018: U.S. Geological Survey data release,


These data were compiled to improve our understanding of how water, carbon (C), nitrogen (N), and phosphorus (P) interact to regulate below ground carbon cycling. Objective(s) of our study were to evaluate how soil heterotrophic carbon cycling responded to inputs of water, C, N, and P individually and interactively on the Colorado Plateau. These data represent soil microbial and CO2 respiration responses to amendments of carbon, nitrogen, phosphorous, and water. Soils were collected at a study site located in Arches National Park in southeastern Utah on 14 August 2017 and again on 17 July 2018 from the upper 10 cm of the soil profile in open spaces among plant canopies after the biological soil crust layer (< 1 cm depth) was removed.

The purpose of these data are to improve our understanding of how carbon, nutrients, and water interact to influence soil efflux of CO2 to the atmosphere, with the potential for large variation in the amount of CO2 released depending on the concurrent spatial and temporal availability of multiple resources. These data were created to conduct three distinct soil incubation experiments to evaluate responses of heterotrophic soil respiration and microbial biomass to different additions of water, C (glucose), N (ammonium nitrate), and P (potassium phosphate). These data could be used by future researchers to better understand how limiting resources interact to affect the dryland carbon cycle for quantifying coupled biogeochemical cycles and effects of climate change at the global scale.
