  abstract = {{C}hanges in land use affect soil properties. {I}n most {W}est-{A}frican farming systems forest-fallow management intended to restore soil fertility no longer functions efficiently because the duration of the fallow periods has been shortened and the fallow areas have been reduced. {A}lternative practices must, therefore, be adopted. {T}his study tested the efficiency of short periods of improved fallows ({A}ndropogon gayanus and {A}cacia holosericea) in regenerating soil microbial properties, compared to the efficiency of a natural long-term fallow. {T}he microbial community was studied by cloning and sequencing 16{S} r{DNA} and by analyzing enzyme activities (alkaline phosphatase, p-glucosidase). {T}he study was carried out at the soil aggregate scale to test how the microbial community in different micro-habitats reacted to the different fallow practices. {T}he 4-year-old {A}cacia holosericea and {A}ngropogon gayanus fallows did not regenerate soil properties as efficiently as the 21-year-old natural fallow. {H}owever, {A}ndropogon gayanus could be used to restore soil properties quickly. {T}hree different aggregate-size fractions were affected by fallow management: organic residues, the > 2000 mu m fraction and the 2-50 mu m fraction. {T}hese microhabitats were enriched with bacteria belonging to the {T}elluria genus and more generally to beta-{P}roteobacteria. {P}ublished by {E}lsevier {B}.{V}.},
