SEM describing the direct and indirect impacts of continuous cropping and soil attributes on species compositions of soil bacterial (a) and fungal (b) communities. Solid red arrows represent the significant direct paths (P < 0.05), while dashed grey arrows indicate the significant indirect paths (P < 0.05)
