Abstract
Recycling empty fruit bunches (EFBs) in mature oil palm stands usually consists in distributing them over a limited area representing 3%–10% of the plot. The impact of this practice on soil quality, including soil biodiversity, is not well known at the plot scale. We analysed soil physical, chemical, and biological variables. Five zones were defined around the palm tree to assess spatial heterogeneity due to plant cover and application of organic and inorganic fertilisers. Each zone was analysed separately. Our study revealed marked variations in mineral contents around the palm tree, ranging from deficiency to excess or nutrient imbalance in adjacent zones, par...
