The objective of this study was to identify a possible acidification and podzolization of the soils under plantation of Pinus caribaea. The study area is located in plated Uberlândia-Uberaba, in the southeast portion of the municipal district of Uberlândia and north of the municipal district of Uberaba (MG). The area presents Latossolos (Oxissols) over basalts of the Serra Geral Formation (Jurassic) and sandstone of the Marília Formations (Meso-Cretaceous) and slopes < 1°. Surface soil samples (0-0.15 m) from three plots in CE and PI were sequentially extracted. Extracts and soil solution were analyzed for Al, Ca, Cu, Fe, K, Mg, Mn, Na, Si, and Zn concentrations, soil solution also for pH and electrical conductivity (EC). Total concentrations in soil solid phase ranged between 94,000-155,000 mg kg^-1 (Al), 29-39 (Ca), 21-31 (Cu), 44,000-61,000 (Fe), 91-141 (K), 21-29 (Mg), 28-57 (Mn), 73-94 (Na), and 13-21 (Zn). Whereas 27-83 % of total K, Ca, Mg, and Na concentrations were exchangeable, > 83 % of total Cu, Fe, Mn, Zn, and Al were bound in hardly plant-available forms. There were no significant differences in concentrations and partitioning between CE and PI. At the beginning of the rainy season (Oct. to Dec.), metal concentrations in soil solution were 2-5 times larger and more variable than between Dec. and Apr. because of the mineralization of organic matter which accumulated during the dry season. Metal concentrations in CE soil solution between Dec. and Apr. were extremely small at all depths (Al: not detected (n.d.)-3.26 µmol l^-1, Ca: 2.8-11.7, K: 0.9-6.7, Mg: 0.7-8.3, Mn: n.d.-0.14, Na: 5.5-40.1, Zn: 0.13-1.02). Up to 1.2 m soil depth, soil solution pH was significantly lower in PI than in CE. Concentrations of Ca, K, Mg, and Na were up to two times larger than in CE, those of Mn and Al 9 and 60 times, respectively. Whereas the soil solid phase did not show significant differences in metal concentrations and partitioning, the soil solution composition clearly indicated enhanced acidification in PI. This resulted in increased leaching of plant nutrients from the topsoil.
