Luvisols (WRB, 1998)
Alfisols (USDA, 1998)
A1
A2
A4
Highly developed soils, loamy or finer textures, low permeable,
with a strongly structured reddish-brown argillic horizon, tongues
or fragipans. They are mainly located on old terraces.
(WRB, 1998: Profondi-Albic Luvisols, Albic Luvisols;
USDA, 1998: Typic Paleudalfs, Fragic Paleudalfs).
Highly developed soils, loamy or finer textures, low permeable,
with a strongly structured greyish-brown argillic horizon, tongues
or fragipans. They are mainly located on old terraces.
(WRB, 1998: Albi-Epigleyic Luvisols;
USDA, 1998: Typic Fragiaqualfs, Fragic Epiaqualfs).
Hydromorphic, poorly drained, developed soils with an argillic
horizon, scarcely recognisable because of the greyish colour of
reduced iron depletions.
(WRB, 1998: Epigleyic Luvisols; USDA, 1998: Typic Epiaqualfs).
Cambisols (WRB, 1998)
Inceptisols (USDA, 1998)

Fluvisols (WRB, 1998)
Entisols (USDA, 1998)
C1
Deep, well drained, scarcely developed soils, with a moderately
structured altered horizon. Rooting and workability are without
limitations.
(WRB, 1998: Dystri-Fluvic Cambisols, Dystric Cambisols;
USDA, 1998: Fluventic Humic Dystrochrepts, Fluventic
Dystrochrepts).
Gravelly, scarcely altered soils, with a weakly structured altered
horizon. Gravels, within 50 cm, limit rooting and workability.
(WRB, 1998: Dystri-Episkeletic Cambisols, Episkeleti-Fluvic
Cambisols;
USDA, 1998: Lithic Humic Dystrochrepts, Lithic Dystrochrepts).
Deep, well drained, not developed alluvial soils, without altered
horizon. No limits of rooting and workability.
(WRB, 1998: Dystric Fluvisols, Dystri-Humic Fluvisols;
USDA, 1998: Umbric Udifluvents, Typic Udifluvents).
Deep, well drained, not developed alluvial soils, without altered
C3
horizon. Gravels, within 50 cm, limit rooting and workability.
(WRB, 1998: Episkeleti-Humic Fluvisols, Episkeletic Fluvisols;
USDA, 1998: Umbric Udifluvents, Typic Udifluvents).
