Abstract

Economic development and environmental concerns have progressed jointly in recent years, increasing the need to mitigate the negative impacts of mechanized forest harvesting, particularly on soil physical quality. In this context, this study aimed to evaluate changes in soil physical properties before and after forest harvesting by simulating machine traffic over different amounts of harvest residues. The experiment was conducted in the municipality of Quedas do Iguaçu, Paraná, Brazil, in a 25-year-old Pinus taeda L. stand owned by the company Araupel S.A. The soil was classified as Dystroferric Red Latosol (Oxisol). A randomized block design was employed, with a split-plot arrangement over time and four replications. The treatments consisted of five levels of harvest-residue cover (0%, 25%, 50%, 75%, and 100%), over which harvester and forwarder traffic was simulated to represent cutting and wood extraction operations. Soil samples were collected before and after machine traffic within the subplots. The results showed that machine traffic caused compaction in the soil surface layer (0–10 cm), regardless of the amount of surface residue. However, the observed compaction levels did not reach critical thresholds that would impair the development of the pine root system.
