With a depth of about 2 to 2.5 m above the water table, these soils show four main horizons from bottom to top: a dark grey horizon with hydromorphic patches (B 3g), dark grey horizon (B 21), dark grey horizon with slickensides (B 1) and a surficial grey humiferous horizon (A 1) with desiccation cracks. Also, they show a heavy clayey texture, very massive structure, high bulk density, very low porosity and a high …
