Are belowground clonal traits good predictors of ecosystem functioning in temperate grasslands?

Dataset contains data on biomass distribution, soil characteristics and trait data for 52 temperate grasslands. Data are presented at community level. Biomass distribution (aboveground biomass, rhizome biomass, and root biomass) and soil chemistry data are original. The trait data are from existing databases and are presented as averages for a community (not weighted by species abundance).
