Phosphorus (P) response prediction based on spatial data in variable soils is to be validated in a series of field trials encompassing different soil types. Best practice for long term management of high P response sites is to be determined.

Using grain protein maps to optimise nitrogen fertiliser to paddock scale nitrogen variability (TCO2423)
Grain protein map data and other spatial data layers will be investigated for application in targeting nitrogen (N) inputs more precisely to optimise N use, grain yield and protein and profitability. A combination of spatial data and targeted small plot N response trials will improve understanding of how to utilise available spatial data layers for variable rate application of N.
