ABSTRACT Traffic of heavy machinery at harvest and log extraction causes structural degradation of the soil, but studies on the effects of forest harvesting on soils with high organic matter content and exchangeable Al are scarce. The objective of this study was to evaluate the effect of mechanized forest harvesting operations on a Dystric Cambisol (Humic) with high organic matter (more 50 g kg1) content and exchangeable Al (more 6,0 cmolc kg-1), reforested with Pinus taeda L. The evaluated harvesting […]

Minas Gerais state is the largest coffee producer in Brazil. The state contributes with over 50 % of the total production, which is for the most part cultivated in the Cerrado region. This region is outstanding in coffee production due to the advanced technology in mechanization. Consequently, the machine traffic that the soils are subjected to causes concern because of the possibility of widespread soil compaction. Our objectives were (a) to propose load support capacity models to a typical dystrophic […]
