Processes controlling DOC in pore water during simulated drought cycles in six different UK peats

The study found that dissolved organic carbon (DOC) concentrations in UK peatlands decrease during drought due to acidification, as measured by acid neutralising capacity (ANC), rather than being primarily driven by soil biota.

• Simulated water table draw-down across all six sites led to a concurrent increase in sulphate (SO4) and a decrease in dissolved organic carbon (DOC), though the strength of this relationship varied by site.
• The decrease in DOC was consistently related to acidification as measured by pore water acid neutralising capacity (ANC), which proved to be a more reliable measure than sulphate alone because it accounts for variations in acid anions and base cation concentrations.
• Rapid increases in DOC following rewetting occurred without a corresponding increase in soil respiration, indicating that DOC levels are primarily controlled by soil acidity rather than soil biota.
