B3	120–145+	Light yellowish brown (2.5Y6/3) with a few distinct fine reddish brown (5YR4/4) mottles; medium heavy clay; weak medium polyhedral structure; smooth ped-fabric; firm moist consistence; many fine manganiferous and coarse ferromanganiferous concretions/nodules with few coarse calcareous soft segregation's; few distinct slickensides and clay skins; very strongly cemented broken nodular ferricrete pan; pH 9.1.
Management Considerations
Texture contrast soil, sodic at depth Leached sub surface horizon, acidic pH Alkaline subsoil with coarse structure roots confined to coarse structure (columnar like). Many ferric nodules in upper subsoil Imperfect subsoil drainage; clayey, coarse structure, moderately dispersive Moderate to high susceptibility to soil structure decline Moderate to high susceptibility to soil compaction, subsurface and upper subsoil Landscape position, long lower slope
