Weathered sandstone.
Management considerations
  • Deep sandy surface soil (ie. 80 cm). Susceptible to wind erosion and sheet erosion
  • Strong texture contrast between sandy surface horizons and clay subsoil. Moderately restrictive to soil water and gas movement
  • Neutral to slightly acid profile, possible multiple profile (sandy accumulation)
  • Surface and subsurface soil have limited absolute nutrients available
  • Subsoil only slightly sodic
  • Crest on ridge, water shedding. Evidence of gully erosion on mid and lower slopes
