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
