Management considerations
  • Cracking clay (vertic) soil.
  • Highly alkaline soils, very slight decrease at depth.
  • Friable self-mulching surface.
  • Surface and subsurface soil are darker than subsoil, more organic matter and very high calcium percentage.
  • Lighter coloured subsoil with poorer internal drainage does not appear till 135 cm.
  • High calcium levels to 100 cm should provide greater stability and structure.
  • Subsoil is strongly sodic and salinity increases at depth (below 115 cm).
  • Landform element, crest: moderate site drainage.
