Using different rates of fertiliser over three different soil types at Cocata locations
Aims

To compare the effects varying fertiliser rates on three different soil types and to compare fertiliser rates, Nil, replacement, standard and high.

Key messages

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.
