%X Arbuscular mycorrhizal fungi community structure is affect by different fertilization but it is unclear how this affects plant growth and nutrient uptake. We studied the effects of 7 different mycorrhizal communities on growth and N, P, K, Cu, Zn, Mn uptake of white clover in pot experiments. The 7 AMF communities were collected from a long-term fertilization field trial, with the following treatments: control without amendment (CK), nitrogen + phosphorus + potassium fertilization (NPK), organic matter fertilization (OM), nitrogen + phosphorus + potassium + organic matter fertilization (1/2OM), nitrogen + phosphorus fertilization (NP), nitrogen + potassium fertilization (NK) and phosphorus + potassium fertilization (PK). The nutrients were applied annually at the following rates N 300kg /hm2 as urea, P2O5135 kg/hm2 as Ca(H2PO4) 2, K2O 300kg/hm2 as K2SO4 with similar rates in the NPK and the OM treatment. The OM treatment consisted of mix wheat straw and fermented soybean and cottonseed, organic fertilizer. For the pot experiment, the soil from a long-term fixed fertilization in Fengqiu was sterilized. All AMF communities had a positive effect on white clover growth, but their effects differed. The AMF colonization rate of the community from the control was significant lower than all other treatments. AMF communities collected from 1/2OM and OM significantly improved P uptake. Compared to CK, most AMF communities improved uptake of N and K; Compared to the other treatments, AMF communities collected from OM, CK, 1/2OM, NP, NK reduced N concentration, and those collected from NPK increased K concentration. The concentrations of Cu, Zn, Mn differed between treatments. These results show that different AMF communities affect growth and nutrient uptake on white clover differentially, probably because of different dominant AMF species which may differ in colonization rate, nutrient transfer to the host and development of hyphae.
