Survival Rates of Microbial Communities from Livestock Waste to Soils: A Comparison between Compost and Digestate

Figure 4

Shannon diversity index detected in (a) sampled soils (n = 4) and (b) livestock waste-based product sources (digestate, wheat straw compost, and woodchip compost) (n = 3). In (a), data are divided by sampling time: w0, week 0; w1, week 1; w6, week 6; w10, week 10; and w14, week 14. The Kruskal–Wallis test resulted in the significant differences among the treatments on weeks 1 and 10; thus, the results based on the pairwise comparison tests were shown in different alphabets. Data are shown as mean ± SD.
