  abstract = {{W}e tested termite mound materials belonging to different feeding groups: {C}ubitermes (soil-feeder), {T}rinervitermes (grass-feeder) and {M}acrotermes (litter-feeder), as natural microbial inoculum to promote plant growth and increase nutrient supplies from soil organic matter and inorganic amendments (rock phosphate), through their effects on soil microoganisms (functional diversity of soil microflora, arbuscular mycorrhizal fungi. rhizobia. fluorescent pseudomonads, actinomycetes and saprophytic fungi). {E}xperiments were made in a pot experiment with {A}cacia seyal, a leguminous tree abundant in {W}est {A}frica, with a sandy soil amended or not with rock phosphate. {R}esults indicated a stimulation of plant growth with {C}ubitermes and {T}rinervitermes mound powder (plant height and shoot biomass), similar to what was obtained with rock phosphate alone. {L}eaf content in {N} was also increased in the termite treatments (except in {M}acrotermes soil), whereas mycorrhizal colonization was inhibited as compared to the control. {T}he development of saprophytic fungi was significantly higher in the soils amended with rock phosphate and this effect was hypothesized to be related to the production of large quantities of oxalic acid by fungal populations. {T}he fluorescent pseudomonad populations notably increased in the soils dually amended with mound powders and rock phosphate., and this could be due to the fact that some species of this bacterial group are able to dissolve rock phosphate. {T}he organic and inorganic amendments decreased the soil catabolic evenness in all the mound powder treatments. {A}mong the mound materials tested, {C}ubitermes mound powder had the most promising effect, especially on {SIR} response to oxalate. {I}t is concluded that soils amended both with rock phosphate and {C}ubitermes mound soil could promote the development of microbial communities, which could help to metabolize this compound and consequently enhance plant growth.
