Figure 3.

Bar chart panels displaying diversity indices for bacteria and fungi across six treatments: SSa, SZa, SLa, SSAFa, SZAFa, and SLAFa. Panel A shows bacterial Shannon index with lower values for SSa. Panel B presents bacterial Chao1 index, with SSa having a distinctly lower value. Panel C depicts fungal Shannon index, also lowest for SSa. Panel D displays fungi Chao1 index, with SSa having the lowest value. Statistical significance is indicated using letters above bars.
