Figure 3

Total soil C (a) and N (b) plotted vs. sand content across depression (red) and slope (yellow) soils in prairie (▲) and switchgrass (●) systems. R2 value marked with * are significant at p < 0.05. Total C and N were significantly higher in prairie than in switchgrass (ANCOVA with sand as a covariate, p < 0.05 and p < 0.1 for C and N, respectively).
