Conteúdo: 	Currently, there is a lack of related studies on the impacts of management in diversified cultivation with oil palm, on the attributes of the soil. Thus, this work aimed to evaluate whether the management affects the physical attributes in different positions within an agroforestry system with oil palm. The research was carried out at an experimental site, in the county of Tomé-Açu, Brazil. The system is called the Biodiverse Agroforestry System (AFS-BIO), with oil palm as the species with the greatest economic value. We collected soil samples with preserved structure in the weeded circle oil palm (WED); harvest path (HAR); leaf pile (PIL) and diversified strip (DIV) in depths 0-5; 5-10; 10-20 and 20-30 cm from the soil, to determine aggregation and bulk density. In management zones without machine traffic, soil aggregation is greater and the density of the soil is lower compared to the harvest path. Machine traffic decreased aggregation and promoted values of bulk density above the ideal (1.4 g cm-3), for sandy loam soils, in the harvest path. The organic management and the presence of mulch on the soil contributed to a higher physical quality, while the heavy machinery traffic in the harvest path causes soil compaction.
