Abstract

Managing agricultural nutrients is important to optimize economic outcomes for agriculture whilst minimizing offsite water quality impacts and associated algal blooms. Whilst much work has been undertaken in WA to understand nutrient transport and transfer processes, and the economic and water quality impacts of various management practices, further work is required to manage soil phosphorus (P) build up, to understand in stream nutrient sources and sinks, to explore different pasture species and potential lower nutrient requirements and to better understand alternative fertilisers and soil amendments. Of prime importance however, and in order to be more strategic in relation to future investment for nutrient management activities, a strong focus on formally documenting and centralizing significant legacy datasets should be the top priority. Current high priority activities such as whole farm nutrient mapping are predominantly technical and extension focussed and can occur largely independently of the formal documentation and centralization of legacy datasets.
