Yuna trial results - soil renovation locations

To explore low risk, best bet strategies for the low rainfall cropping zone.

Key messages
  • Repellence can be worse below 5cm (5-10cm samples collected but not tested yet).
  • If repellence is worse at 5-10cm this may explain why deep ripping has increased repellence as ripping could bring some of this more water repellent soil to the surface.
