Plant biomass is affected by soil treatment.

(A) Bars represent mean total dried biomass across all field soils and all autoclaved field soils with SE. The asterisks indicate statistically significant differences [ANOVA tests with P ≤ 0.05, n = 537]. (B) (C) Box plots of differentially abundant OTUs found across all live soil history [ANCOM (Mann-Whiteny U + FDR correction P ≤ 0.05, n = 201)].
