Management Considerations

Texture contrast soil, sodic and at depth.
Neutral to alkaline subsoil with coarse structure, roots confined to coarse structure.
Few (variable) 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 (loose surface).
Landscape position; crest, well drained site drainage.
