A Venn diagram displaying the degree of intersection of bacterial OTUs clustered at 97% sequence similarity among the different treatments. Different samples display different color, number in the diagram represents the shared or unique OTU number. Overlap region represents shared OTU number, while non-overlap region represents unique OTU number. The OTUs differed among the four treatments and their numbers were 5740 (P), 6186 (PS), 6847 (PW) and 7067 (PSW). P is the control treatment (none straw neither earthworms), PS is treatment with rice straw, PW is the treatment with earthworms and PSW is the treatments with both rice straw and earthworms
