The soils, especially the Spodosols, of the “restinga”, a coastal plain, are poorly studied and understood in Brazil. In this work, the micromorphology of spodic horizons was investigated at four sites of the coastal plain of the State of São Paulo (Bertioga, Ilha de Cananeia, Ilha do Cardoso, and Ilha Comprida). This allowed the characterization of different organic matter forms.  These data, together with macromorphology, were used in the analysis of the main processes involved in the genesis of spodic […]
