  1. a One to seven peat samples were analyzed from one peat core section at irregular intervals from top to bottom [24, 28]
  2. b Inorganic composition of each peat sample determined from loss on ignition at 750 °C for > 1 h [28]
  3. c See Additional file 1: Appendix S1 for a detailed derivation
