Abstract Fagus silvatica L. inoculated or not with the ectomycorrhizal fungusLaccaria laccata and/or a phosphate-solubilizing rhizobacterium,Agrobacterium radiobacter, was cultivated in a greenhouse in lysimeter cylinders containing rock phosphate and a mica (phlogopite) as the only sources of P, Fe, Mg and Al. After two years, beech dry matter and P, Mg, Fe and K uptake were higher for plants inoculated—either withAgrobacterium radiobacter or withLaccaria laccata, but not for those plants inoculated with both micro-organisms—than for uninoculated plants. Mineral element mobilization from rock phosphate and from phlogopite was also greater when plants were inoculated with the bacteria or with the ectomycorrhizal fungi. Such mineral element dissolution can be related to the increased root growth but also to the amount of organic acids released in the rhizosphere. The absence of significant effects of dual inoculation suggested competition between micro-organisms.
