The current calibration curves between a particular soil test and crop grain yield responses are based on a large body of past research. However, cropping systems in WA have changed. For example, there is now a wider range of crop species growing in rotations, increased adoption of zero-till, increased crop yield, and more nutrients need to be managed for optimal crop grain yield. Thus there is a need to improve the current soil test-crop response calibrations to maximise returns from fertiliser investment in cropping.
