Uncemented discontinuous nodular ferricrete and manganiferous pan; brown (7.5YR4/3);

Dusky red (2.5YR4/4);
light medium clay; strong medium polyhedral, parting to strong fine subangular blocky structure; pH 6.7.

Management Considerations

  • Strong texture contrast between surface (top)soil and subsoil
  • Sandy, acidic and hydrophobic surface soil, susceptible to sheet and rill erosion
  • Ferric (ironstone) pan, restrictive drainage, more lateral movement
  • Slightly acidic to neutral subsoil
  • Red subsoil indicates reasonable site drainage (movement of water and gas) given texture contrast nature of profile
  • Landform element is a hillslope, moderately well to well drained site drainage
