Restinga is a term currently used for the vegetation on the poor and sandy soils of the coastal plains of Brazil. The soils of these environments have been poorly studied. The counties Cananéia, Ilha Comprida and Bertioga were selected for this research due to the representativeness of the environmental conditions of the state of São Paulo. In these environments 31 soil profiles were described and sampled, many of them in chronosequences. The samples were characterized chemically and analytical evidence converged […]

In spite of modern and sophisticated techniques, procedures of selective dissolution are still of considerable value for soil characterization and to the understanding of the pedogenetic process, especially environments and soils poorly studied, as the coastal plain regions and Spodosols of Brazil. The application of these techniques commonly used for characterization of spodic horizons and soil profiles for large amount horizons and soils studied in cronossequences are rare for those environments and become possible to establish comparisons with those intensively […]
