This projects aims to better understand the factors controlling nutrient retention and removal within agricultural catchments and how climate and land use change will affect this. This project will combine novel approaches to investigate nutrient sources, removal and bioavailability with geochemical tracers to better understand nutrient flow and removal pathways. This new knowledge will be captured in state of the art modelling approaches that will help improve land management practices, leading to reduced nutrient loads and improved water quality in receiving waters such as the Gippsland Lakes.

该项目旨在更好地了解控制农业集水区内养分保留和去除的因素，以及气候和土地利用变化将如何影响这一点。 该项目将联合收割机与地球化学示踪剂相结合，采用新的方法研究营养物质的来源、去除和生物利用度，以更好地了解营养物质的流动和去除途径。 这些新的知识将通过最先进的建模方法获得，这将有助于改善土地管理做法，从而减少诸如吉普斯兰湖等受纳沃茨的营养负荷并改善水质。
