DOC and CO₂-C Releases from Pristine and Drained Peat Soils in Response to Water Table Fluctuations: A Mesocosm Experiment

Figure 3

Mean (±SE) soil water pH in different experimental groups at different phases of the study. for each experimental group and each phase. pH values were converted to H⁺ concentrations (mol H₃O⁺ L⁻¹) before the statistical analysis. Significant differences between the experiment groups are indicated with asterisks (). W: water sampling; H: high water table; (xx): calendar week number. Pr: pristine; Dr: drained; Ctrl: control; Fluc: fluctuating water table.
