This project improved irrigation management in potatoes and onions, augmenting results from previous projects in other vegetables. The project had two components: firstly, it conducted detailed experiments at Gatton Research Station, confirming best practices for irrigating potatoes and onions. A concurrent strategy focused on monitoring irrigation practices with collaborating producers, demonstrating irrigation management techniques in commercial circumstances. These on-farm sites involved installation of tensiometers in crops, with monitoring several times per week, to record changes in soil water status.
