[This dataset is embargoed until August 30, 2027]. This dataset contains information about soil biogeochemical parameters from a lab manipulation experiment that was part of a study testing freeze-thaw and drought effects on alpine soil microbial communities and biogeochemistry. The soil was collected from Vent, Austria in March 2021. It was then shipped to the Soil and Ecosystem Ecology Lab at the University of Manchester, where the experiment was conducted in April - August 2021. Various soil biogeochemical properties were measured on destructively harvested samples at five experimental timepoints. The soil samples had been subjected to different treatment combinations throughout the experiment (see lineage for details). For details on each parameter, see the supporting documentation.
