  abstract = {{T}his study considers the relationship between microbial diversity and soil organic decomposition function of two soils whose microbial diversity was first established using molecular biology ({DGGE}) and in situ catabolic potential ({ISCP}). {T}he soil used was a tropical ferruginous {O}xisol, with samples taken from a 21-year fallow and a plot that had been {C}ultivated for 4 years after lying fallow for 17 years. {T}he samples from the 0-10 cm soil layer were incubated with or without the addition of {F}aidherbia albida litter under laboratory conditions (28 degrees {C}, 100% {WHC}) for 240 h. {D}uring incubation, the microorganism activity was measured ({CO}2, mineral {N}, phosphatase, beta-glucosidase and urease). {I}n the unamended soil, the activity of the microorganisms was greater in the fallow soil which had a greater microbial diversity than that in the cultivated soil. {H}owever, other soil properties (carbon and organic nitrogen content, total microbial biomass) may also explain this result. {F}or the amended soil, only the first 8 h of incubation showed a difference between the fallow and cultivated soil. {D}uring this period, the {CO}2 respiration in the fallow soil was higher than that recorded in the cultivated soil. {T}his difference should be compared with the catabolic microbial diversity, which was higher in the fallow soil than in the cultivated soil. {A}fter this initial phase, the microbial community in the cultivated soil seemed to acquire similar functions to those in the fallow soil. {T}he phosphatase and beta-glucosidase activities of the amended soils were higher in the fallow soil. {T}his difference was maintained for the whole incubation period. {T}he redundancy of microbial functions is discussed.
