Phosphorus management in Oxisols using cover crops and organic acids

E-mail: Quintin.Gravatt@anu.edu.au

The aim of this project is to develop cover crop practices for the heavily fertilised potato cropping soils of the Robertson district that will minimise erosion and runoff of water, potentially rich in phosphorus (P), thereby resulting in significant improvements in the environmental management of this sensitive catchment area. The cover crops will improve infiltration, decrease erosion, and off-site transport of P and increase access to accumulated soil P, making it available to a subsequent potato crop, thus decreasing the P loading of the soil.
