Assessing the yield response to deep ripping over two soil types near Beverley, Western Australia locations
Aims

To assess the impact of deep ripping on crop yield in different soil types and production zones near Beverley, WA.

Key messages
  • Assessing yield responses on different soil types will guide where future deep ripping work is carried out, with priority given to those soils with the greatest yield increases.
