Fig. 2 Soil-level plant-soil feedback (PSF). Each panel shows the PSFs for a plant species across eight soil types. Soil types are defined by the plant species that cultivated them. Solid and dotted lines are from fall 2017 and fall 2018, respectively. Each value derived from target plant biomass in 14 plots with ‘home’ soils and 15 plots with ‘away’ soils. Error bars represent 95% confidence intervals of bootstrapped values. Red, black and blue values represent negative, neutral and positive PSFs, respectively. Species abbreviations listed in Fig. 1.
