Sombric-like horizon and xanthization in polychrome subtropical soils from Southern Brazil: implications for soil classification

The occurrence of dark subsurface horizons rich in organic matter (OM) associated with polychrome in the B horizon (yellowish over reddish hue) is common in soils from Southern Brazil. The formation of these horizons and the combination with such mor
