Figure 4

Pore size distribution for > 18.2 μm radius pores from topographical depressions (a) and slopes (b) in prairie (▼) and switchgrass (●) cropping systems before plant growth experiment. Shown are means with error bars representing standard errors (n = 6). Lower case letters indicate significant differences between topographical positions within each planting system (p < 0.05); upper case letters indicate significant differences between the cropping systems within each topographical position (p < 0.05).
