This study analyzed, the impact of Feller Buncher and Skidder traffic in harvesting areas of eucalyptus in Mogi Guaçu, considering the compaction and fertilization effects in the range of soil next to the carrier during the cycle of forest growth. An increase in soil compaction, caused by machinery traffic in topsoil (0-10 cm), was observed in the area recently harvested. The soils of the study areas, with eucalyptus 1.4 and 6.0 years old, showed good fertility conditions, especially the older area, where decomposition of forest residues possibly contributed to such fertility.
