Fig. 3: Solid-phase speciation of added 57Fe.
From: Iron-mediated organic matter decomposition in humid soils can counteract protection
57Fe partition was calculated from respective Mössbauer spectra (corrected to exclude the signal from the native soil Fe) for the (a)  57Fe-only and (b) 13C-DOM-57Fe addition treatments, prior to the oxic phase (day 1) and at the end of the 1st oxic (day 6), anoxic (day 17) and 2nd oxic (day 22) phases. Error bars represent standard errors associated with Mössbauer data modeling (see Supplementary Information).
