Figure 1

Images of sugar-treated model soils over time (a); the far left panel is an uninoculated sterile kaolinite and sand mixture, and the far right panel is the same mixture, inoculated and treated with weekly glucose additions for 15 months. Relative abundance of chemical compound groups in substrate (Time 0) and model soils amended with (b) sugar, (c) syringol and (d) plant dissolved organic carbon (DOC). These are compared to soil collected from an agricultural field (e). Glucose and cellobiose treatments were averaged since there were no significant differences in their chemistry (ANOVA: P>0.05). Numbers above bars are the total number of identified compounds.
