Pie charts depicting the relative abundance (% of total sequences) of bacterial groups in the original soil (S0) and in the soils at the end of the microcosm experiment (S64: untreated soil after 64 days of incubation; SG: sewage sludge treatment; SB: soybean meal treatment; WS: wheat straw treatment). The triplicates of each soil are denoted as (A–C).
