  abstract = {{T}he {S}ahel of {W}est {A}frica has vulnerable agroecosystems that threatens food security. {A} potential solution is intercropping with the indigenous shrub, {G}uiera senegalensis {J}.{F}. {G}mel. {P}revious research of the {O}ptimized {S}hrub-intercropping {S}ystem ({OSS}) (high density of similar to 1,500 shrubs ha(-1) and coppiced residue incorporation) has been shown to dramatically improve pearl millet [{P}ennisetum glaucum ({L}.) {R}. {B}r.] yield, which is attributed to improved soil quality, nutrient and water availability, and harboring a distinct microbial community. {W}hether this response is consistent over a climate and soil type gradient in farmers' fields has not been investigated. {T}herefore, the objective was to determine the impact of {G}. senegalenis on soil chemistry, enzyme activity, microbiomes, and metabolic pathways of millet root zone soils in farmers' fields. {T}he experiment was a three-by-two factorial with three rainfall and soil type sites along a north-south gradient in the {S}enegal {P}eanut {B}asin and two sampling locations (millet root zone soil within and outside the influence of the {G}. senegalensis). {G}uiera senegalensis shifted certain predicted bacterial metabolic pathways and enriched some bacterial and fungal genera. {N}otably, the increased crop growth due to {G}. senegalensis positively correlated with the abundance of genera having plant growth promoting properties (e.g., {E}nterobacter agglomerans and {P}araburkholderia). {P}aucibacter, a genera that has deleterious and/or pathogenic properties, was highly abundant in non-shrub soil but completely suppressed beneath the shrub. {T}he results showed that {G}. senegalensis in farmers' fields even at typical, low densities, where coppiced residues are annually burned, still increased soil chemical and microbial properties, suggesting that a more important factor than litter is the presence of shrub roots that provide root turnover and exudates, and water inputs through hydraulic lift.},
