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

A research paper investigating the drivers of dissolved organic carbon (DOC) dynamics in six UK peatlands during simulated drought cycles, finding that DOC decreases are consistently linked to acidification (measured by acid neutralising capacity) rather than solely by sulphate levels or soil biota.

• Simulated water table draw-down across six sites in Great Britain resulted in a simultaneous 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 incorporates acid anions and base cation concentrations.
• Following rewetting, DOC levels increased rapidly without a corresponding increase in soil respiration, indicating that soil acidity, rather than soil biota, was the primary control for DOC changes.
