The Mallee Sustainable Farming Zonal N Management tool has been developed to help farmers and advisers understand the zonal N management decision:
- where do I put the first unit of nitrogen fertiliser?
- when do I stop and start putting fertiliser somewhere else?
- how are these decisions affected by my 'gut feel' about the season?
Users should appreciate that the EC1:5 values used to represent soil types have some meaning in the MSF Mallee, but that they might not relate well to the properties of all soils in the Mallee and especially outside the Mallee. Even then, using them as a gauge of 'responsiveness' (high EC1:5 = less responsive) might still make the tool valuable as a way of understanding the dynamics of the decision.
People looking for answers to specific decisions, particularly in-crop, should consult their agronomist or Yield Prophet.
| Disclaimer: This is a beta (preliminary) version of the tool, and has not been properly validated. We would welcome comments and suggestions. People who use the tool do so at their own risk, and although we have taken great care putting it together, Mallee Sustainable Farming, Mallee Focus and all others take no responsibility for any adverse outcomes of its use.

This (Oct 6 2010) is a 'beta' version of the tool and likely to change over the next few weeks. If you would like updates when this happens, please subscribe to the site RSS feed (above). Alternatively, put your email in when you download, or use the 'Update' option from the 'File' menu of the tool.
Grateful acknowledgements to Anthony Whitbread and David Gobbett, of CSIRO Sustainable Ecosystems, for their efforts put into getting good simulations with APSIM of the crops (wheat in the Mallee at Carwarp, Euston, Loxton and Pinnaroo) that underpin this work.
