Abstract

Abstract: Soil microbial communities, key players of many crucial ecosystem functions, are susceptible to environmental disturbances, which might cause the loss of microbial diversity and functions. However, few ecological concepts and practices have been developed for rescuing stressed soil microbial communities. Here, we manipulated an experiment with or without arbuscular mycorrhizal fungi (AMF) inoculation and at three levels (one, three and six species) of plant diversity to disentangle how the AMF and vegetation rescue soil nitrogen (N) ‐cycling microbial loop from simulated degraded soil ecosystem. Our results showed that AMF inoculation improved the restoration of soil N‐cycling microbial communities. This improved restoration was related to the role of AMF in enhancing interactions within the N‐cycling microbial loop. Furthermore, increased plant diversity strengthened the role of AMF in rescuing N‐cycling microbial communities. Our findings provide novel insights into the roles of AMF and plant diversity in facilitating the rescue of microbial communities in degraded terrestrial ecosystems.
