• Texture contrast soil or deep sand over clay.
• Deep sandy material is alkaline at the surface becoming neutral to slightly acidic with depth.
• Deep loose sand, bleached, little nutrient holding capacity or available.
• Sandy material susceptible to wind and sheet erosion.
• Upper subsoil is acidic becoming alkaline with depth.
• Subsoil is sodic with pale colour and mottling, restricted drainage.
• Landform element, dune; well drained site drainage.
