We assessed whether the composition and plant growth promotional effects of a synthetic AMF community can be altered by inoculum additions of the isolates forming the community. We found a transient positive response in AMF abundance to intraspecific inoculation only in the competitively weakest isolate. The other two isolates responded negatively to intra- and interspecific inoculation and in some cases plant growth was also reduced. Our results suggest that increasing AMF density may lead to increasing competition among the fungi and a tradeoff with their ability to promote plant productivity. This is a key ecological aspect to consider when introducing AMF into soils.
