Crop nutrient decisions in the high rainfall zone (HRZ)
Commercial wheat and canola crops in the high rainfall zone (HRZ) of southern Australia typically yield well below the yields that have been achieved in trials that were well supplied by nutrients. A previous report concluded that this was because insufficient fertilizer was applied to achieve the potential yield, and that the main barrier to supplying sufficient nutrients was a lack of confidence that the higher rates required would result in an economic return on investment. This report updates progress from this project (DAV00141) and related projects. It also proposes the future direction of the project to help agronomists and growers to get the best outcome when growing wheat and canola.
