Management Considerations:
  • Sodic and strongly dispersive subsoil is likely to restrict root and water movement down the profile.

Comments from Landholder:
  • Mallee cleared 1890.
  • Continuously cropped with grains (barley, oats, wheat) and legumes (peas, faba beans).
  • Crops ripen earlier than in other areas.
  • Direct drilling used as cultivation method.
  • Super phosphate, gypsum (with ripping) and nitrogen applied.
