Quantitative comparisons of bacterial species diversity represented by the alpha diversity metric – Faith’s Phylogenetic Diversity –in the bulk soil and rhizosphere soil at all time-points. The median as well as the 25th and 75th percentile of the samples is presented, individual data points outside of this range are given as mean ± standard deviation of three replicate samples. Significant differences due to crop sequences within one compartment (bulk soil or rhizosphere) are noted. The dark blue boxplot represents the canola-soybean sequence (Ca-S), light blue boxplots are the soybean-soybean sequence (S-S) and the purple boxplots are the corn-soybean sequence (C-S). (A) Comparison of cumulative phylogenetic diversity of the bacterial community in the bulk soil and rhizosphere soil treatments. (B) Comparison of cumulative phylogenetic diversity of the fungal community in bulk soil and rhizosphere soil for all crop sequences and all time points. Statistical significance was analyzed by the Kruskal-Wallis test. Asterisks indicate statistically significance (P < 0.05).
