Improving phosphorus use efficiency and return on investment in high Phosphorus (P) fixing soils of the Southern and Western Regions
Aims to improve growers’ certainty about managing phosphorus (P) in high-fixing soils, which have chemical properties that bind applied P, making it unavailable to crops. The project outcome is that by 2030, growers in the Southern and Western regions will access improved P fertiliser application strategies to maximise return on investment (ROI) in high P fixing soils.
The project will be delivered as three interlinked components:
- Component 1 (Output 1) will be a comprehensive review of research from relevant previous projects to identify knowledge gaps and inform the design of the other two components.
- Component 2 (Outputs 2, 3 and 4) will apply insights from Component 1 through regionally tailored paddock-scale trials and demonstration trials. These trials will test best-bet P management strategies and generate actionable data to support grower decision making.
- Component 3 (Output 5) will explore new and novel solutions to improve Phosphorus Use Efficiency (PUE).
