The soils of the ribeirão Cambé hidrographic basin located at Londrina, PR, Brazil, were studied. An area of 75 kmz shows five soil classes: Iatossolo roxo distrófico (LRd); terra roxa estruturada distrófica/eutrófica (TRd/e); terra roxa estruturada latossólica eutrófica/distrófica (TRLd/e), hidromórficos (Hi) and litólico eutrófico (Re). All of them have high acidity, small activity clays and are predominantly distrophics. Those soils are organized in two soil systems: the first one, where latossolic soils predominate (pedoenvironment 1, at NW of the area), and the second one, where litholic soils and ultisols occur (pedoenvironment 2, at SE of the basin). The pedoenvironment 1, located at a urban-rural site, must be used in accordance with its geotechnical parameters, while the pedoenvironment 2, basically rural, must be managed following the agronomic capacity of its soils.
