  abstract = {{T}he {A}frican oil palm ({E}laeis guineensis {J}acq.) is grown on a total area of 16 million ha; but data on soil quality in mature oil palm plantations are fragmentary and data concerning biota are almost nonexistent. {C}onsequently, no well-tested sampling method is available for soil diagnoses. {W}e studied the spatial heterogeneity of the soil around the palm by measuring comprehensive soil quality in a 24-year-old oil palm plantation. {S}oil quality and litter were assessed in five zones with different plant cover, and different applications of herbicide or fertilizer. {P}hysical-chemical characteristics, macrofauna, and nematofauna were analysed. {A} sampling method was developed and adapted to the way the cultivation practices are implemented: sampling by zone and weighting the plot mean by the respective area of each zone. {T}he total density of macrofauna in the litter and in the 0-15 cm soil layer followed a gradient from the harvest pathway (29 ind m(-2)) to the windrow (1003 ind m(-2)). {A}nts (13-237 ind m(-2)), earthworms (11-120 ind m(-2)), {D}ermaptera (0-35 ind m(-2)), {C}oleoptera (3-24 ind m(-2)) and {C}hilopoda (0-43 ind m(-2)) were the main taxa. {T}he termite population was very poor (3-4 ind m(-2)). {T}he density of nematofauna was also heterogeneous (268-805 ind 100 g(-1) of soil). {H}eterogeneity between zones was also reflected in the density of the functional groups, mainly soil engineers, detritivores and predators for macrofauna and bacterial feeders, and phytoparasites for nematofauna. {T}he weeded circular zone around the palm had the highest soil nutrient content ({P}, {K}, {C}a, {M}g, {C}-org {CEC}, base saturation). {I}ts biodiversity was average but it contained the highest density of earthworms and nematofauna. {P}ossible relationships between chemicals and biological groups in the food web are discussed.},
