Última Relationship between soil oxidizable carbon and physical, chemical and mineralogical properties of umbric ferralsols Rev. Bras. Ciênc. Solo Marques,Flávio Adriano; Calegari,Márcia Regina; Vidal-Torrado,Pablo; Buurman,Peter. The occurrence of Umbric Ferralsols with thick umbric epipedons (> 100 cm thickness) in humid Tropical and Subtropical areas is a paradox since the processes of organic matter decomposition in these environments are very efficient. Nevertheless, this soil type has been reported in areas in the Southeast and South of Brazil, and at some places in the Northeast. Aspects of the genesis and paleoenvironmental significance of these Ferralsols still need a better understanding. The processes that made the umbric horizons so thick and dark and contributed to the preservation of organic carbon (OC) at considerable depths in these soils are of special interest. In this study, eight Ferralsols with a thick umbric horizon (UF) under different vegetation types...
