The Victorian Department of Economic Development, Jobs, Transport and Resources (DEDJTR), is Australia's leading agriculture research and development organization. Better managing N to meet production and environmental goals is a high priority. DEDJTR highly values international collaboration and recognizes the benefits of international harmonization of methods, practices and tools targeting N use efficiency. To that end, DEDJTR is proposing to work in close collaboration with a number of international research groups from New Zealand, USA and Europe on improvement of farm scale management of the nitrogen cycle,, with an emphasis on using an farm level N budgeting approaches. This will support the development of on-farm and catchment indicators and methods to quantify nitrogen utilization, identify sources of nitrogen losses, quantify various pathway losses and develop strategies to minimize environmental impacts.
