  abstract = {{S}oil organic carbon ({SOC}) contributes to agrosystem productivity. {U}nderstanding how farming practices implemented by smallholders affect the levels and distribution of {SOC} in carbon ({C}) pools with different stabilities is essential in sub-{S}aharan {A}renosols where {SOC} mineralization is intense. {T}he stability of {SOC} was studied by thermal ({T}herm-{C}), physical (particulate organic matter >50 mu m, {POM}-{C} and fine soil fractions <50 mu m, {FF}-{C}), chemical (permanganate-oxidizable carbon, {POX}-{C}) and biological (mineralizable {C}, {M}in-{C}) approaches. {S}oil samples were collected at depths of 0-10 and 10-30 cm in cultivated fields (out- or home-fields) without any input, with millet residues, amended with manure, or with household organic wastes. {G}lobally, average {SOC} contents were low (<6 g {C} kg-1). {T}he variability in {SOC} and {C} pool contents was sensitive to field management. {T}he different approaches to measuring the stability of {SOC} did not measure the same fraction of {SOC}. {POM}-{C} and {T}herm-{C} were correlated and both explained {M}in-{C} similarly, thus suggesting that in these sandy soils, {POM}-{C} or {T}herm-{C} probably measured comparable properties of the stability of {C}. {T}he lack of relationships between {POX}-{C} and other pools suggested that {POX}-{C} encompassed a different nature of {SOC} while providing complementary information on the biogeochemical stability of {SOC}.},
