Microbial community structure in soils under different CCs and residue management: (a, d) Canonical analysis of principal coordinates (CAP) showing effect of CCs (and residue, for fungi); (b, e) Beta diversity as dispersion between different plots within each CC treatment, including betadisper results; (c, f) Heatmaps showing changes in the relative abundance of microbial phyla. In heatmaps, color gradient represents average relative abundance expressed as centered log-ratio (clr), and CC treatments are indicated by colored bars. R−/R+ refers to main crop residues absent or present, respectively. Heatmaps were created with R package ‘gplots’ (github.com/talgalili/gplots).
