  abstract = {{T}he rhizosphere is a hotspot of interactions between plants and soil organisms that affect the soil functioning and nutrient cycling. {T}he drilosphere is a hotspot of interactions between earthworms and soil microbial communities affecting plant growth, soil aggregation, and porosity. {C}entral to these interactions are microorganisms, which are affected by both plant species diversity and earthworm activity. {L}ittle is known about the effects of earthworms on the microbial community activity under the influence of root-trait diversity in cases of multispecies plant covers. {W}e investigated the impact of plant composition and the presence of endogeic earthworms on the metabolic response of microorganisms to the addition of 10 carbon substrates relevant as rhizodeposition components. {A} greenhouse experiment was conducted with mesocosms filled with 10 kg of soil, sown with two plants of either the same or different species, chosen based on their contrasting root traits. {F}ive modalities were investigated: 1 faba bean ({V}icia faba {L}. ssp. {M}inor) intercropped with either 1 rapeseed ({B}rassica napus {L}.) or 1 wheat ({T}riticum aestivum {L}.) plant, as well as crops of the same species: either 2 rapeseeds, 2 wheats, or 2 faba beans. {F}or each modality, 10 mesocosms were set up, and half of them were inoculated with 5 endogeic earthworms ({A}porrectodea caliginosa {S}avigny). {A}fter 91 days, the plants' dry weight, {N} content, and 15{N}:14{N} ratio were measured. {T}he rhizosphere microbial respiration was assessed using the {M}icro{R}esp{TM} method. {T}he results showed that the level of metabolic activity depends on the plant species composition. {F}aba bean had the highest positive effect on microbial growth and metabolic activity. {M}icrobial activity was also significantly increased by earthworms, but with no specific effect between plant treatments. {O}ur findings suggest that plant traits are the main driver of the metabolic activity of soil microorganisms that is stimulated by earthworms.},
