  abstract = {{P}lant-parasitic nematodes are injurious crop pests that have been managed mainly by chemical nematicides. {H}owever, safe and alternative methods such as those based on organic materials need to be developed. {O}ur study has evaluated (i) the effects of four organic amendments with different biochemical compositions that are abundantly produced in the study area ({G}uadeloupe, {F}rench {W}est {I}ndies) on soil nematode communities and (ii) some of the suppression mechanisms of banana parasitic nematodes, especially those involving the soil food web. {T}his study is based on a microcosm experiment comparing sugarcane bagasse, sugarcane sludge, plant residues and sewage sludge. {A}ll amendments except sewage sludge decreased the root abundances of plant-parasitic nematodes, by 96% in the case of sugarcane bagasse. {F}or this treatment, soil densities of carnivorous nematodes were six times higher than the treatments without organic amendment. {P}lant residues and bagasse were mainly composed of materials that are difficult to decompose, namely cellulose and lignins. {T}hese organic materials favored a fungal decomposition pathway and permitted development of carnivorous nematode populations and increased the {C}hannel {I}ndex ({CI}). {P}ratylenchus coffeae control after sugarcane refinery sludge application remains unexplained. {L}astly, sewage sludge, composed mainly of easily degradable compounds, did not permit nematode control, and only bacterivorous nematode populations were enhanced by this treatment.},
