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 |
The soil samples taken from the different paddock zones at the beginning of the year showed varying levels of P across the different zones. Where the NDVI was high in 2009, the levels of P were generally lower than in the low NDVI zones of the same year. Anecdotally this can be attributed to the higher NDVI zones using more of the P for the higher production levels than the lower NDVI zones. |
