  abstract = {{P}hytate is considered a poorly available plant {P} source but proved to be useful for particular soil bacteria strains. {I}n soil-free conditions, it has been shown that bacteria locked up the mineralized phosphorus from phytate whereas bacterial grazers like nematodes were able to deliver {P} to plants. {H}ere, we aimed to determine if the interactions between phytate-mineralizing bacteria, bacterial grazer nematodes, and mycorrhizal fungi could increase plant {P} acquisition from phytate in high {P}-adsorbing soils. {P}inus pinaster was grown in a {C}ambisol supplemented with phytate. {P}lants, whether associated or not associated with the ectomycorrhizal fungus {H}ebeloma cylindrosporum, were either inoculated or not inoculated with the phytase-releasing bacteria {B}acillus subtilis and the bacterial-feeding nematode {R}habditis sp. {A}fter 100 days, the dual inoculation of bacteria and nematodes significantly increased net plant {P} accumulation. {W}e observed that, on average, mycorrhizal plants accumulated more {P} in their shoots than non-mycorrhizal plants. {H}owever, the highest plant {P} acquisition efficiency was found when the three soil organisms were present in the {P}. pinaster rhizosphere. {W}e conclude that, in a highly inorganic {P}-fixing soil, plant {P} acquisition from phytate strongly depends on the grazing of phytate-mineralizing bacteria. {O}ur results confirm the importance of the soil microbial loop to improve plant {P} nutrition from phytate, which should be considered a route to improve the utilization of this source of poorly available {P} by plants.},
