Figure 4From: Effects of Prescribed Fire at Two Frequencies on N Mineralization and Nitrification at Two Spatial Scales in Mixed-Oak ForestsFire frequency effects on soil N turnover and organic C content in relation to sample plot size. Means and standard errors of the means are shown (N=33 for each 50 m2 macroplot and N=25 for each 1 m2 microplot), and bars labeled with the same lower case letter were not significantly different at p<0.05.Back to article page
