More profit from nitrogen

Project details

Status: Completed

TIA is a major partner in the national ‘More Profit from Nitrogen’ project that aims to increase farm profitability and reduce environmental impact by increasing nitrogen use efficiency in cotton, dairy, cherry, mango and sugar industries.

In collaboration with the University of Melbourne, TIA is leading a sub-project using farm system analysis and modelling capacity and capability to validate recommended nitrogen best practice on dairy farms.

This data will help the industry increase home grown forage consumption, reduce total feed cost and achieve a reduction in greenhouse gas emissions.

Main activities will include:

  • modelling the potential interactions between soil N mineralisation, N application rate, and climate for the major dairy regions of Australia
  • Establishing farm systems modelling simulations, to examine the potential whole of farm benefit using the findings from the experimental field trials
  • Modelling the interacting influences of irrigation management, fertiliser timing and the use of enhanced efficiency fertiliser (EEF) on pasture production and nitrogen use efficiency (NUE)
  • Identifying best combinations of irrigation, fertiliser timing and EEF type at a the whole farm systems scale
  • Communicating finding through field days conducted at the research sites, focus farms, farmer and service provider discussion groups, industry newsletters and industry conferences
  • Updating the Dairy industry’s Fert$mart website and Australian Dairy Soils and Fertiliser Manual and provide service provider training days.

The project is supported by funding from the Australian Government Department of Agriculture and Water Resources as part of the Rural R&D for Profit program.
