Espodossolos in Brazil: A review of the criteria and conceptualization of the spodic B horizons [PDF]

open access: yesRevista Brasileira de Ciência do Solo
The absence of quantitative limits for the diagnostic attributes that define spodic B horizons in the Brazilian Soil Classification System (SiBCS) allows the inclusion of soils in the Espodossolos (the equivalent of Spodosols or Podzols) classes that
