This study was conducted under field conditions, in order to determine the effect of pineapple crop (Ananas comosus L.) residues on the edaphic arthropod fauna. Slips were planted in June, in Red-Yellow Latossol , with crop residues in amounts of 0, 30 and 60 t/ha, placed on the surface or tilled under 10cm, with and without 10% (v/v) Agrobio biofertilizer applied along with the residues and sprayed monthly at 3% (v/v) two months after planting. Soil samples were collected from the top 5.0 cm of soil at 90, 210, 330 and 450 days after the application of residues. Over 15 months, the predominance of Acari and Collembolan was observed. The highest density of animals was observed in the first sample, at 90 days after the addition of residues. Nevertheless, differences in soil fauna abundance between treatments were not detected until 330 days after soil management with crop residues.
