Summary
Australia has a negative potassium (K) balance with approximately 3 times more K removed from the system than applied across agricultural areas. Increasing instances of K deficiency on heavier textured soils has been seen and how best to manage this issue has been raised at NGN forums.
Building on the current body or research and linking to existing investment in the Western region, this investment will target two key components that require RD&E to improve growers' confidence in K fertiliser management to maximise return on investment (ROI):
(1) the tools required to identify paddocks and regions at risk of K deficiency across diverse soil types (different CEC levels and mineralogy) in the GRDC Southern and Northern regions, and
(2) fertiliser management strategies tailored to soil types and climatic regions (K rate, placement and formulation) to match crop demand with nutrient availability and maximise ROI.
Offer period
Offers will remain open for acceptance by the GRDC for a period of 6 months after the Closing Time.
