Principal coordinate analysis (PCoA) describing the effects of experimental treatments on the taxonomic composition of soil prokaryotic communities. Coordinates 1 and 2 explain the highest variability for all experiments (85.5%) (a), see supplementary Table S6. Statistically significant differences between samples using non-parametric Kruskal–Wallis and Mann–Whitney tests (*p < 0.05) (b), see supplementary Table S7. S1 and S2—unamended soils; S1SL and S2SL—soils amended with sewage sludge, SL—sewage sludge.
