Restinga is a typical vegetation on quartzitic, sandy, nutrient-poor parent materials along the Brazilian coast. Soils under restinga vegetation on the Ilha do Cardoso (SP) were studied to understand their genesis and to improve the Brazilian Soil Classification System (SiBCS). Thus, a physical, chemical and detailed morphological characterization was carried out. The results evidenced aquic, sandy, very acid soils with variable organic matter content, in which podzolization is the main pedogenic process. Sulphidric materials also occur due to the influence […]
