Investigating ways to boost profits from more efficient nutrient use in WA cropping systems

DPIRD researchers, led by Dr Craig Scanlan, have been investigating nitrogen (N), phosphorus (P) and potassium (K) crop use efficiency, soil storage and yield responses.

The current body of evidence used to support N, P, and K decisions is inadequate across a range of situations and this uncertainty has led to some lack of grower confidence in fertiliser recommendations.

These decision gaps exist in N, P and K fertiliser management because of climate and systems changes that have occurred after most crop nutrition knowledge was first documented in WA.

GRDC project codes: DAW1801-001TRX & UWA1801-002RTX
