Data for "Why are graminoid species more dominant? Trait-mediated plant-soil feedbacks shape community composition"

This dataset includes the plant biomass data, plant-soil feedback data, and simulation model code (includes parameters).  We want to clarify that the simulation model code used in our study is not novel (developed by Dudenhöffer et al. 2022) and has been duly cited in the main text. We only modified some parameters, which we have made explicit in the main text.
