Changes in the composition of the bacterial community in soils used for traditional crops and American ginseng. a PCoA ordination plots show the relatedness of samples that were separated using weighted UniFrac distances of classified 16S rRNA gene sequences. b The relative abundances of the bacterial community (>1%) at the phylum level. TF and AGF refer to soil samples from traditional farmland and American ginseng farmland, respectively. An asterisk denotes a significant difference between TF and AGF at P < 0.05. The value of each bar represents the mean ± SD of n = 3
