Technology considerations for cost-effective subsoil loosening

Key points

• Deep ripping tyne technologies vary in their ability to loosen, mix, delve and rearrange clods within the profile
• Key strategies to minimise costs include:
  • rip no deeper than necessary;
  • optimise timing (soil moisture);
  • operate above the tyne critical depth;
  • add wings to tynes when operating deep.
• Opportunities exist for optimising multi-depth tyne layouts and spacings for maximum loosening efficiency and reduction of total draught
