Fig. 3. Denitrification potential of four wetland plants by three bases of plant matter addition. Note, although there were significant differences (p < 0.01) in denitrification potential (±1 SE) on both a dry weight and total C basis, changing the basis to acid-soluble carbohydrates (ASC) reduces the significance of plant-specific differences (0.1 < p < 0.9).
