gcb2485-sup-0001-fS1-AA.pdfapplication/PDF1350KFigure S1.  Overview of soil properties and soil profile picture (sample date: 05-03-2010): (a) soil moisture profile (vol%) under fully flooded conditions, (b) bulk density profile (gcc−1), (c) calculated total porosity (%), (d) C/N ratio and (e) picture of soil profile. The upper 50–55 cm is dominated by peat with the main root zone occupying the top 25–30 cm. Carbonate rich organic silt is the dominating deposit at a depth of 55–60 cm.
