P-Efficient Pastures- Del. High N & Water
Phosphorus (P) is the primary nutrient input that drives legume growth and nitrogen fixation in the pastures of southern Australia. However, P-fertiliser costs have doubled since 2000 and a tightening in future supply is anticipated. Both factors are expected to lead to a steady increase in fertiliser costs, increasing cost of production.
This project aims to reduce the phosphorus dependence of Australian farmers by delivering pasture systems that require less phosphorus fertiliser. This will achieve multiple benefits including nitrogen use efficiency, water efficiency and improved productivity for Australia’s pasture systems. The project will also develop the knowledge and necessary protocols to equip and inform farmers about how to improve their phosphorus efficiency.
