Shannon H’ diversity for 16 S, internal transcribed spacer (ITS) and ITS-oomycete (ITS-OOM) libraries from Healthy and Unhealthy soil samples. All libraries were rarefied to the same number of reads prior to alpha-diversity calculations, 5000 reads/sample for 16 S and ITS, and 1000 reads/sample for ITS-OOM. There were no significant differences between Shannon values for H and UH soil in either the bacterial (16 S) fungal (ITS) or oomycete (ITS-) communities (Kruskal-Wallis, p > 0.05).
