Additional file 1: Fig. S1. Hyphal length density (pot expt 1), patch N2O concentrations (pot expt 1) dissolved organic carbon content, and total carbon and nitrogen contents (pot expt 2) in patches in the absence or presence of AMF. A, pot expt 1. Hyphal length density from different patches under −AMF and +AMF treatments (n = 8). B, pot expt1. Dynamic N2O concentrations from different patches under −AMF and +AMF treatments after the addition of NO3−-N or NH4+-N (n = 4). Control, soil patch; NSfaba and Sfaba; patches with unsterilized (NS) or sterilized (S) faba bean residues, respectively. C-F, pot expt 2. Dissolved organic carbon (C), hyphal length density (D), total carbon (E) and total nitrogen (F) content under the −AMF and +AMF treatments at both harvests (n = 5). T1 and T2, the first (day 24) and second (day 34) harvests, respectively; asterisks, significant differences between the −AMF and +AMF treatments in each patch type (pot expt 1) or at each harvest (pot expt 2) according to two-tailed unpaired t-tests (*, P < 0.05; **, P < 0.01; ***, P < 0.001).
