Results of ANOVAs on the effect of the experimental variables on microbial community.

Impact of plant diversity (plant species richness (PSR, log transformed) and number plant functional groups (FG)) and presence of distinct plant functional groups (legumes, grasses, small herbs, tall herbs) on total microbial biomass (MicBM), Gram-positive (Gram+), Gram-negative bacteria (Gram−), fungal biomass (Fungi) and the composition of the soil community, characterized by the fungal-to-bacterial biomass ration (F:B ratio). Numbers in bold display p values < 0.05 and numbers in italic display p values <0.1.
