| Deppe, M; Blodau, C: Humic acid addition lowers methane release in peats of the Mer Bleue bog, Canada., Soil Biology and Biochemistry, 52, 96-98 (2012) | |
| Abstract: The effects of humic substances on methanogenesis in peats are poorly understood. In incubation experiments we added Pahokee Peat Humic Acid (DOM), a suppressor for methanogenesis (2-bromoethane sulfonic acid, BES), and BES + DOM to bog peat and studied CO2 and CH4 release. Addition of DOM lowered CH4 (p < 0.05) but not CO2 release compared to controls. BES addition suppressed CH4 release compared to controls (p < 0.01). DOM/BES addition lowered the release even further (p = 0.06) but did not induce net CH4 loss. DOM was thus utilized as electron acceptor and lowered CH4 release; anaerobic CH4 oxidation may have contributed to this effect. |
