Management considerations
  • Strong texture contrast soil,
  • Slightly acidic surface soil becoming neutral at depth
  • Sandy surface profile, slightly susceptible to sheet and rill erosion and limited nutrient availability
  • Internal drainage affected by subsoil texture, lateral flow likely
  • Poorly structured profile, subsoil grading into weathered parent material (rock)
  • Landscape position; midslope, moderately well drained site drainage
