The More Profit from Nitrogen Program (MPfN) is a four year partnership between Australia’s four most intensive users of nitrogenous fertilisers: cotton, dairy, sugar and horticulture. The Program is conducting research and development to the increase nitrogen use efficiency (NUE) across the four sectors whilst improving profitable and sustainable use. By better understanding the influence of contributing factors on NUE in farming systems, the Program is:
- Generating greater knowledge and understanding of the interplay of factors to optimise N formulation, rate and timing across industries, farming regions and irrigated/ non-irrigated situations;
- Generating greater knowledge and understanding of the contribution (quantifying rate and timing) of mineralisation to crop or pasture N budgets; and
- Generating greater knowledge and understanding of how enhanced efficiency fertiliser (EEF) formulations can better match a crop or pasture specific N requirements.
The Program is supported by $5.889 million funding from the Australian Government’s Rural Research and Development (R&D) for Profit program in addition to cash and in-kind contributions from each of the industry sectors, research organisations and collaborating partners equating to $9.757 million.
The MPfN Program is at the mid-way point of research activities but is already resulting in a more collaborative research effort to accelerate aligned research methodology, standardising terminology to reduce confusion for industry end users and communicating NUE outcomes using common indicators across the four industry sectors. MPfN is a proactive collaboration formed to expedite NUE across Australia’s intensive cropping and grazing industries to reduce environmental impact and increase the long-term sustainability of Australian farming businesses by increasing yield, product quality and overall profitability
