This publication covers findings from Mallee deep sandy soil research that shows the impacts of tyne design and features on the energy efficiency and loosening effectiveness of deep ripping.

Key points

• Deep ripping is a soil amelioration technique. Australian cropping farms in the southern region use this technique on sandy soils. Deep ripping allows roots to access subsoil water and nutrients.
• Different designs and features of deep ripping tynes each have a different impact on:
  • energy efficiency and
  • effective soil loosening.
• Research conducted in Mallee deep sandy soils shows the different impacts on deep ripping effectiveness of:
  • five narrow shank ripper tynes. with and without wings, and
  • five delving/mixing ripper tynes.
• This fact sheet will help growers maximise the effectiveness of their deep ripping program by choosing the right tynes and equipment for their situation.
