The community composition and diversity of arbuscular mycorrhizal fungi (AMF) can be affected by several factors, including the climate, soil biota and host plants. This study aimed to evaluate the influence of Sesbania virgata (SV) revegetation in pure and intercropped with plantation Eucalyptus camaldulensis (EC) and Acacia mangium (AM), in the composition and diversity of arbuscular mycorrhizal fungi (AMF), and the amount glomalin-related soil protein (GRSP) in an area damaged by clay extraction. The experimental design was a randomized block with four treatments (planting pure SV - 100SV); consortium of SV + EC - 50SV: 50EC; consortium AM SV + - 50SV: 50AM) and degraded area with natural vegetation - ADVE) and three replications. Revegetation of mining digging clay with SV in pure or intercropped planting reduced the abundance of spores and increased species diversity of arbuscular mycorrhizal fungi. Furthermore, increased the amount of glomalin-related soil protein compared with the degraded area and spontaneous vegetation.
