  abstract = {{A}cacia nilotica var. tomentosa trees from the {D}iarra protected forest located in the {S}enegal {R}iver valley were identified for the assessment of both biological nitrogen fixation, using the natural abundance method, and soil bio-functioning parameters (nodulation, root biomass, total microbial biomass, and potential {N} mineralization). {T}he presence and the genetic diversity of indigenous rhizobia nodulating {A}. nilotica var. tomentosa was also investigated, taking into account distance from the trunk (0, 1, 2, and 3 m) and depth (0-25, 25-50, and 50-75 cm). {S}urprisingly, no nodules on the trees root systems were found, whereas under laboratory conditions the presence of indigenous rhizobia nodulating {A}. nilotica var. tomentosa was demonstrated in the analyzed soils (90% of the nodules harvested on the trapped plants were occupied by the same {I}nter-{G}enic {S}pacer ({IGS}) group, {IGS}1). {T}here was no significant influence of trees and/or depth on total microbial biomass and potentials of nitrogen mineralization. {S}ome assumptions were formulated on the possible combined effect of flooding, which usually occurs annually during 4-7 months, and the clayey soils in the {D}iara forests. {A}lthough a deeply natural nodulation of {A}. nilotica var. tomentosa trees by indigenous rhizobia is not excluded, but it still remains to be demonstrated.},
