Values are % of population +/- S.E. derived from the taxonomic summaries of the three different biological replicates. Taxonomy is listed based on Phyla (Kingdom: Bacteria) under biochar amendment and no biochar amendment (control). Significant differences are noted by different letters (mean n = 3; ± s.e.) compared to the control.
