Figure 1

Distribution of the top 25 abundant bacteria at the phylum level and their cluster analysis under different treatments as visualised by heatmaps (variables clustering on the vertical axis). CK: untreated soil; B: soil treated with biochar; B + U: soil treated with biochar and urea; Urea: soil treated with only urea as nitrogen fertilizer; BCRNF: soil treated with BCRNF as nitrogen fertilizer. The colour intensity of the scale indicates the relative abundance of each phylum. Relative abundance is defined as the number of sequences affiliated with that taxon divided by the total number of sequences per sample (%).
