Fig. 4. Boxplots showing the relationship between cumulative saturation and the abundance of redoximorphic features in loamy textured horizons for the 18 mo-long study period. The three outliers from the 66 data points were removed before statistical analysis. A one way analysis of variance and Tukey's multiple comparison tests were used to determine differences between means. Means of boxplots with different letters are significantly different at the 0.05 level. Values below the x axis indicate the number of horizons having this class of redoximorphic feature (RMF). * indicates outliers.
