  abstract = {{T}his study reports on the distribution of nematodes in different soil habitats under a permanent pasture of digitgrass (#{D}igitaria decumbens$ {S}tent. cv. "{P}angola") in {M}artinique. {T}he objectives were to evaluate a gentle fractionation method compatible with further soil nematode extraction and to assess the respective soil microhabitats of plant-feeding nematodes and free-living nematodes. {T}his study indicated that the gentle soil fractionation can effectively separate soil habitats and allow the recovery of associated nematodes. {P}lant-feeding nematodes were equally distributed between inter-aggregate pores, habitats constituted of aggregated fine silt + clay particles and roots + rhizosphere. {M}ost of free-living nematodes (53%) resided in the inter-aggregate pores. {I}rrespective of food resource, densities of nematodes (number per gram of habitat) were similar in habitats coarser than 1000 micrometres ({A}5000, {A}2000 and {A}1000). {H}abitats with the finest soil ({A}200) were not favourable sites because of the rarity of roots (for plant-feeding nematodes) and physical constraints.
