  abstract = {{I}n agrosystem field experiments, earthworm inoculation did not impede depletion of soil organic stocks in most cases, in spite of increased carbon inputs through enhanced primary production. {S}light evidence of soil organic matter ({SOM}) protection was found in poorly structured soil, such as a yam plot in {I}vory {C}oast (soil sieved before experimentation), and a pasture plot on {M}artinique. {A}ggregation inherited from past earthworm activities probably maintains {SOM} protection after earthworms have disappeared ; longer term experiments are necessary to observe {C} dynamics after the disappearance of inherited earthworm structures. {I}n two experiments with maize in {I}vory {C}oast and {P}eru, the activity of earthworms led to a small increase in the incorporation of organic matter from surface mulch in the {SOM}. {M}ost of the {C} incorporated into the {SOM} originated from root material, and earthworm activities only slightly modified this pattern. {E}arthworm activity had significant effects on the distribution of {C} among particle size fractions. {T}he general trend was a depletion of large (greater than 50 micrometers) particles and an accumulation of small (less than 2 micrometers) particles. {N}utrient depletion in low-input cropping systems was not impeded by earthworm activities ; at {Y}urimaguas, some signs of a better conservation of {K} were noted after 3 years in the traditional rotation.
