Rates of AOM and SR in different natural terrestrial habitatsa
| Location | Soil depth (cm) | Methane (mM) | Sulfate (mM) | AOM rate | SR rate | Reference |
|---|---|---|---|---|---|---|
| Wetland and peat soil | 0–40 | 0.5–1 | 0.1–1 | 265 ± 9 nmol cm−3 day−1 | 300 nmol cm−3 day−1 | 206c |
| Tropical and boreal soils | 10–15 | <1 | 3-21 nmol gdw−1 day−1 | 138b | ||
| Paclele Mici Mud Volcano in Carpathian Mountains | 1.5–2 | 2-4 nmol gdw−1 day−1 | 118b | |||
| Peat land soil from diverse places | 30–50 | 0.03–3 nmol gdw−1 day−1 | 207b |
