Fig. 3. Variation in mean weight diameter (MWD) in the soil profile, before and after wettings. Initial is the MWD value in the soil profile before wetting. Each value in this figure is the mean of three replicates. The depths are reported as the midpoint. Bars represent the least significant differences (LSD) between treatments at P 0.05. Treatments at each depth marked by different letters are significantly different.
