Soil properties and microbiome for the collection sites. A The soil texture measured in proportions of sand, silt, and clay and B a principal component analysis of soil elemental composition and pH, arrows represent loadings of elements and pH on principal components 1 and 2. C Taxonomic barplots depicting the relative abundance of the top ten phyla subdivided into the top three classes, phyla below the top ten are condensed into the “Low Abundance Taxa” category. D Principal coordinate analysis on Bray–Curtis dissimilarity for soil samples. For both panels B and D, the colors correspond to collection sites
