Increasing profit from N, P and K fertiliser inputs into the evolving cropping sequences in the Western Region
This project aims to give GRDC's Western Region grain growers increased confidence in decision making around fertilisers with a focus on nitrogen (N), phosphorus (P) and potassium (K). As a result an improved N decision support model will be delivered. The work will include modelling of economic responses to N, P and K management strategies, update nutrient decision guidelines and disseminate findings broadly to GRDC's Western Region grain growers.
