Table 1.
Total nitrate reduction, denitrification (DNF) and dissimilatory nitrate reduction to ammonium (DNRA) integrated across the duration of the flow through reactor experiment.
| Nitrate reduction (mmol per cm3) | DNF (mmol per cm3) | DNRA (mmol per cm3) | DNRA + DNF (mmol per cm3) | ||||||
| Depth | Mean (M) | Standard deviation (SD) | M | SD | M | SD | M | SD | Percentage of nitrate reduction |
| Shallow (0–5 cm) | 87.5 | 7.4 | 70.6 | 1.7 | 10.2 | 0.6 | 80.9 | 1.8 | 92 |
| Mid (10–15 cm) | 61.3 | 4.1 | 58.1 | 3.7 | 4.8 | 1.4 | 63 | 4.0 | 102 |
| Deep (20–25 cm) | 70.9 | 20.4 | 55.2 | 10.3 | 3.6 | 0.9 | 58.8 | 10.3 | 82 |
Note: The sum of DNF and DNRA accounted for between 82%–102% of the total amount of nitrate reduced during the experiment. The data were derived from Bulseco and colleagues (2019). Abbreviations: cm3, cubic centimeters; mmol, millimoles.
