In the south of Brazil, there are soils presenting darker subsurface horizons than those overly-ing ones, being more representative in Ultisols. Those ones are placed in well-drained areas and do not present sodium saturation. In dark subsurface horizon, these soils shows morpho-logical aspects similar to sombric horizons, initially related to Central Africa. This fact arise the possibility of these soils meet the sombric horizon, as related in Africa. The definition of sombric horizon showed in Soil Taxonomy has been the same for fifty years, without any important modification. In this definition the sombric horizon consists of iluvial humus not associated with aluminum or sodium. In WRB, its definition is almost the same of Soil Tax-onomy...
