The objective of this GRDC / SPAA funded project is to increase the level of adoption of PA 'beyond guidance' by broadacre farmers. The project specifically aims to increase the level of adoption of variable rate (VR) by growers in the project to 30% by 2013.This goal will be achieved by demonstrating how to use PA tools to growers at a regional level and by increasing the skills of growers and industry in PA to a level where they can then use PA tools in their farming systems to achieve economic, environmental and social benefits.

| Other trial notes |
There was no interaction between EM38 and Yield or nitrogen application. There was a similar effect on lentils as seen in the trial at Arthurton, where lentil yield declined as EM value increased. The results of this trial may be more related to the season then any paddock variability, as the 2010 season again showed that timing is just as if not more important than amount of rainfall received. Regular rainfall and a cool finish meant crops were not moisture limited and roots did not need to seek much subsoil moisture to finish. |
