Longevity of deep ripping on deep white sands in a CTF system locations
Aims

This trial aims to establish the long-term value of deep ripping on compacted deep south coast sands. It investigates the longevity of the ripping benefit in a fully controlled traffic system (CTF).

Key messages
  • Rip to below your compacted layer
  • Ripping to 60cm reduced soil strength, and this effect continued into the second year after ripping
  • Wheat yield response to the 60cm rip treatment paid for deep ripping in the first year
  • It is important to understand potential yield benefits of ripping before you rip
