The communities of arbuscular mycorrhizal fungi (AMF) and saprotrophic fungi in the rhizosphere under manure treatments. a AMF biomass. b Saprotrophic fungal biomass. c Diversity. d AMF community composition. Bars (n = 3) with different lowercase letters indicate significant differences as revealed by Tukey’s HSD tests (P < 0.05). NLFA, neutral lipid fatty acid; PLFA, phospholipid fatty acid. M0, no manure; M1, low manure; M2, high manure; M3, high manure plus lime
