Maximising de-compaction and minimising water repellence in sandy soils at Binnu, 2015 - dune site  locations
Aims

Identify profitable long term management of subsoil compaction for deep sandy soil at Binnu.

Key messages
  • Ripping to 550mm increased yeild in the deep pale sand (Dune) and yellow loamy sand (swale).
  • Topsoil slotting, with soil inclusion plates attached to the rear of deep ripper tines, can increase yeild from deep sandy soils more than by deeper ripping alone.
  • Deeper ripping with topsoil slotting also helped lessen grain losses from dry and hot spring weather.
  • If slotting maintains the de-compaction response longer it will provide very good returnson investment.
