VRT of seed and fertilser across land classes locations
Aims

To compare the effects VRT on different soil tyes and to compare rates of seed and fertiliser.

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.

Other trial notes

Using VRT allows redistribution of fertiliser into more responsive areas and in the heavier boron prone sub soil region allows the opportunity to cut rates. Previous work done in this area has shown reducing seeding rates in the poor zones allows a better grain fill during poor seasons.
