Figure 2From: Fire Effects on Nitrogen Cycling in Native and Restored Calcareous WetlandsChanges of the extractable NOX-N and NH4-N of the soil in the burn plots and control plots in the restored wetlands (Res2000) and reference wetlands two days, one month, and one year after the fire. The black bar represents the value before fire. The star (*) denotes significant difference between the burn plots and control plots (P < 0.05).Back to article page
