  abstract = {{U}nderstanding the spatial stability of the plant-feeding nematode ({PFN}) community in agrosystems represents a fundamental step in the integrated control of some damaging species because modifications of soil properties in intensively managed agrosystems may allow growers to manipulate the balance between pathogenic and non-pathogenic species. {I}n the present study, we tested the hypothesis that a community of four {PFN} species ({C}riconemella onoensis, {H}elicotylenchus erythrinae, {H}emicriconemoides cocophillus, and {P}ratylenchus zeae) in a sugarcane agrosystem is spatially structured according to macro-scale soil properties. {T}his hypothesis was studied by using a sugarcane field in {M}artinique in which soil properties had been heavily modified by hillock-leveling in the 1970s, resulting in a great variation in soil properties over a small area (20.8 x 16.0 m). {T}he goal of the study was to measure the temporal stability of the {PFN} community spatial structure and to identify the soil parameters associated with differences in nematode abundance. {A} systematic sampling design was used to collect data in the field that were analyzed using co-inertia and {STATIS}-{C}oa. {T}he field study was complemented by a greenhouse experiment. {T}he field study documented the existence of a stable spatial pattern of the {PFN} community, a pattern that was structured in relation to macro-scale soil factors such as soil carbon, nitrogen, and phosphorus content and soil texture. {T}he constant spatial pattern of the {PFN} community results from the differences in distributions among {C} onoensis and the three other {PFN} species. {C}. onoensis was consistently more abundant in the deeply-leveled areas of the field, while the other {PFN} species were more abundant in the non-leveled areas. {H}. etythrinae was consistently more abundant in those parts of the field with higher soil p{H} and sodium content. {T}hese results suggested that soil properties can affect permanently the competitive balance among {PFN} species. {T}he observed relationships between {PFN} and these macro-scale factors were validated in a greenhouse experiment with different ratios of soil from the leveled and non-leveled areas of the field site. {M}odification of some major soil properties (p{H}, {N}a+ content, soil organic content) by cultural practices such as hillock-leveling, fertilization, and liming, could greatly affect the balance among {PFN} species in agricultural fields.},
