Average values of chemistry clades by sample type (†based on heatmap clustering in Fig 1, mud-LA3-S and mud-LA3-O were included as soils due to their chemical similarity to other soils).

Within-column values with the different super script letters were significantly different from one another as determined by Tukey’s HSD: pH of bagasse vs. soil = 2.7553 (p = 0.0009); mud vs. soil = 1.722 (p = 0.0057). P2O5 of bagasse vs. mud 2.0476 (p = 0); mud vs. soil = 1.8543 (p = 0); C:N of bagasse vs. mud = 74.469 (p = 0); bagasse vs. soil = 60.3313 (p = 0.0003).
