Total organic carbon (%) (a), Thermal stability index (R index) (b), thermal lability index (I index) (c), spring above ground plant biomass (d), summer above ground plant biomass (e), total yearly above ground plant biomass (f) measured at the plot level within the TwinWin during two consecutive years. Growth (g), respiration (h) and CUE (i) observed in the rhizosphere of barley along the undersown plant diversity gradient (log). Significant relationships were evaluated with linear mixed models with location in the field (block or plot) as random effect and are presented by solid lines when significant (p < 0.05); exact p values are given next to the R2 values (n = 167, df = 163). The shaded area denotes 95% confidence intervals around the mean values. Source data are provided as a Source Data file.
