Micromorfologia de horizontes espódicos nas restingas do Estado de São Paulo

Abstract: RESUMOOs solos de restinga são pouco estudados e conhecidos no Brasil. Neste trabalho, a micromorfologia de horizontes espódicos foi investigada em quatro locais do litoral do Estado de São Paulo (Bertioga, Ilha de Cananeia, Ilha do Cardoso e Ilha Comprida). A técnica possibilitou caracterizar as diferentes formas da matéria orgânica, e, juntamente com a descrição morfológica de oito perfis de solos representativos das restingas do Estado de São Paulo, objetivou-se discutir os mecanismos envolvidos na gênese d… Show more

“…Many areas observed in the thin sections had organic matter coatings completely filling the porous space, with a porphyric distribution pattern (Fig. 4c, 4e), a phenomenon already observed by Coelho et al (2012) in spodic horizons formed in sandy materials from the coast of São Paulo state, Brazil. However, basic types of relative distribution such as chitonic, gefuric and enaulic can be observed in the thin sections of the spodic B horizons (Fig.…”

“…4a). The organic matter in the spodic horizons, characterized by the advanced stage of transformation and absence of cellular structures or original forms of vegetable remnants, can be identified as monomorphic (De Coninck et al, 1974;Coelho et al, 2012).…”

“…The Bhm horizon of the P6 profile is formed in the contact zone (Pos-Barreiras/Barreiras Formation), and studies indicate that the difference in porosity between soil layers influences the origin of spodic horizons (Coelho et al, 2012;Gomes et al, 2017). Therefore, in the profile, the Barreiras Formation hinders the infiltration of water, and consequently, the illuviation of dissolved organic matter, favoring the formation of the Bhm spodic horizon (Figure 2e).…”

“…They get to grow into gigantic Spodosols (Coelho et al, 2012). Spodosols can be identified by the color of the spodic horizon that can be gray, dark gray, black, red or yellow, and by the sharp differentiation of horizons.…”
