  abstract = {{A}n experiment was conducted over nine months in a field system in northern {S}enegal in order to determine the effects on soil nitrogen ({N}) cycling and the microbial biomass-{C} properties of five plant species proposed for the {S}enegalese {G}reat {G}reen {W}all ({GGW}): {A}cacia senegal ({L}.) {W}illd., {A}cacia tortilis var. raddiana ({S}avi) {B}renan, {B}alanites aegyptiaca ({L}.) {D}el., {B}oscia senegalensis ({P}ers.) {L}am. ex {P}oir., and {S}clerocarya birrea ({A}. {R}ich.) {H}ochst. {S}oil samples were collected to a depth of 0-10 cm, outside (control) and beneath tree canopies. {M}icrobial biomass, inorganic {N} content and net mineralization of organic {N} were determined for the soil samples collected under trees, and compared to soils collected outside tree canopies. {T}he results showed that concentrations of inorganic {N} and soil microbial biomass-{C} were generally higher under canopy cover and differed according to species. {I}n {M}ay 2014 (end of the dry season), microbial biomass-{C} was higher under {A}. senegal (31.8 mg {C}/kg soil) and lower under {B}. senegalensis and in the control sample from outside the canopy (17 mg {C}/kg soil). {A} higher microbial biomass-{C} content was found under {A}. senegal (49 mg {C}/kg soil) and {B}. aegyptiaca (53.7 mg {C}/kg soil) in {O}ctober 2014 (end of the rainy season) and in {J}anuary 2015 (middle of the dry season). {I}n {M}ay 2014, the concentration of ammonium was significantly higher under {B}. senegalensis (11.17 mu g/g soil), while the control sample (outside the canopy) had the lowest concentration (4.93 mu g/g soil). {F}or nitrates, there was no significant difference between canopy species ({P} <= 0.05). {T}hese results can provide guidance for selecting tree species for the {GGW} according to their functioning and their effects on soil quality.},
