  abstract = {{R}ecycling empty fruit bunches ({EFB}s) in mature oil palm stands usually consists in distributing them over a limited area representing 3%-10% of the plot. {T}he impact of this practice on soil quality, including soil biodiversity, is not well known at the plot scale. {W}e analysed soil physical, chemical, and biological variables. {F}ive zones were defined around the palm tree to assess spatial heterogeneity due to plant cover and application of organic and inorganic fertilisers. {E}ach zone was analysed separately. {O}ur study revealed marked variations in mineral contents around the palm tree, ranging from deficiency to excess or nutrient imbalance in adjacent zones, particularly in available {P} and {K}, {M}g and p{H}. {S}imilar variations in macrofauna were observed both in the litter and the soil. {O}ur results demonstrate that the changes caused by plant cover and applications of fertiliser are mainly limited in space, but that earthworm communities move as a function of variations in nutrient availability or stress associated with {EFB} deposition over time. {T}he {A}macher index, adapted to the soil nutrient status for oil palm, indicated that average mineral fertility at the plot scale was rather good. {T}he average density of soil macrofauna and nematofauna was low compared to other tropical ecosystems, but reference data from {I}ndonesia are lacking. {A}pplication of {EFB}s on the harvest path mainly improved the homogeneity of soil quality within the elementary plot around the palm. {H}owever these data did not show that recycling {EFB} stimulates soil fauna communities or carbon sequestration at the plot scale.},
