Mean isoprene consumption rates from four depth intervals incubated in the laboratory at 25°C
| Depth interval (cm below surface) | Consumption rate (pmol gdw−1 day−1)a | SM (% dry weight) | LOI (%)b | pH |
|---|---|---|---|---|
| 0–3 | 585.48 ± 6.94 | 35.15 | 6.54 | 5.63 |
| 3–6 | 468.41 ± 20.88 | 37.83 | 7.04 | 5.60 |
| 6–9 | 394.05 ± 5.71 | 44.59 | 8.43 | 6.30 |
| 9–12 | 378.81 ± 11.80 | 49.87 | 8.98 | 6.33 |
a
Values are means ± standard deviations for four replicate experiments at each depth interval.
b
LOI, loss on ignition, determined by dry combustion at 625°C for 6 h, to estimate soil organic matter content.
