Characterization of a toposequence in National Park of Serra da Canastra, MG

O estudo foi desenvolvido no Parque Nacional da Serra da Canastra - PNSC, localizado no Estado de Minas Gerais, em uma área protegida de 50.000 ha. O objetivo foi caracterizar os solos de uma topossequência na Serra da Canastra, localizada no PNSC, organizada do topo para a base, conforme a seguinte variação de vegetação: Cerrado Sentido Restrito, Campo Limpo e Campo Limpo Úmido com murundo. Foram descritas as seguintes classes de solos: Latossolo Vermelho Ácrico típico, Latossolo Vermelho Ácrico húmico, Cambissolo Háplico Tb Distrófico típico, Cambissolo Húmico Tb Distrófico típico, Cambissolo Húmico Tb Distrófico latossólico e Gleissolo Háplico Tb distrófico típico.The study was conducted in the National Park of Serra da Canastra - PNSC located in the state of Minas Gerais with 50.000 ha of protected area. The objective was to characterized a toposequence in the Serra da Canastra Plateau organized from the top to the base with the following grassland with murundus. It was determined the Acric Dystrophic Oxisols, Acric Humic Oxisols, Dystrophic Haplic Cambisols, Dystrophic Humic Cambisols and Dystrophic Haplic Gleysols. The Oxisols had a very clay texture located in a convex hillslide with flat top, with flat tops, with Wooded Savannah and Grassland. The Humic and Haplic Cambisols are presented between Oxisols in a straight hillslider with a clay loam texture and in a Grassland physiognomy. The Haplic Gleysols werw placed towards the end of the toposequence in water logging environment with from clay to very clay texture in a Humid Grassland physioognomy. All classes showed Horizon A prominent or humic with organic matter above 20 g.kg-1, and high levels of gibbsite increasing from top to the base of the toposequence and parameters attributed to acric soils
