Weathered sandstone.

Management Considerations

Texture contrast soil.
Very deep sandy hydrophobic surface soil, susceptible to wind ,sheet and rill erosion.
Slightly acidic upper surface to alkaline subsurface and subsoil.
Weakly developed sodic clayey subsoil.
Duneslope, well drained site drainage.
