Management Considerations:

Texture contrast soil, sodic and at depth.
Leached sub surface horizon.
Alkaline subsoil with coarse structure, roots confined to coarse structure.
Many ferruginous nodules/sandstone in deep subsoil.
Imperfect to slow subsoil drainage; clayey, coarse structure, highly dispersive, may be vertic at depth.
Moderate to high susceptibility to soil structure decline.
Moderate to high susceptibility to soil compaction, subsurface and upper subsoil.
Landscape position, long lower slope.
