Ocupando areas menores, ocorrem os Cambissolo Haplico--CX (Cambisol), Neossolo Fluvico--RU (Solo Aluvial), Planossolo Haplico SX (Planosol Solodico) e Afloramentos de rocha associados a Neossolo Litico.
The soil types were a Red Sodosol (Isbell 1996) or Orthic Solonetz (FAO 1998) at the Gunyah Eroded and Gunyah Scald profiles, a Red Sodosol (Isbell 1996) or Mollic Solonetz (FAO 1998) at the Gunyah Vegetated microsite, and a Red Kurosol (Isbell 1996) or Solodic Planosol (FAO 1998) at the Gunyah Pasture profile.
Los tipos que predominan en la zona son Planosol eutrico, Xerosol haplico, Planosol molico, Xerosol luvico, Feozem haplico y Fluvisol eutrico (INEGI 1981).
The soil is classified as hypereutrophic sodic salic Haplic Planosol (Miranda, 2010), with predominantly sandy loam texture (EMBRAPA, 2006) (Table 1).
In general, both maps show patterns similar to the predicted soil units, with the exception of the ACce unit (Haplic Acrisols Clayic + Haplic Planosol).
The soil in this location is classified as Hydromophic Eutrophic solodic Planosol with Francosilty texture.
