The aim of the report is to educate the reader as to the importance of TE"s, how to apply them, and to then generate discussion around the use of them more widely within agriculture ix and the food industry... Evan Ryan RYANAGPTYLTD 0428 298 031 03 5744 3662 ev_ryan@hotmail.com To assess the importance of trace elements in broadacre farming and to study methods to manage their application and benefits Currently few Australian broadacre farmers are using trace elements to increase their productivity and profitability Travel across North America and Europe interviewing farmers, researchers and advisors who use and recommend trace elements Trace elements are important both to plant growth and to human health... Trace element use can improve productivity and profitability for farmers and improve health outcomes for consumers...

The nitrogen recovery in grain was calculated for all treatments (yield t/ha x protein % x 1.75)... The data from the trials was inconclusive in determining an optimal growth stage for application although the highest protein result was achieved from application during late head emergence to early milk at seven of the eleven sites... Although early application of additional nitrogen can cause canopy management issues, these results (in years with erratic or low spring rainfall) support the need to get nitrogen on early...

Early or preventative foliar sprays, applied from GS32 onwards on moderately susceptible varieties, have provided the best returns in northern trials over the last three years High grain prices and low fungicide costs mean breakeven yield benefits required are often only 1-2% Application can be the major cost of treatment Consider timing when stripe rust in area but not in crop or in tank mixture with a late herbicide, near GS32, to eliminate extra application cost.. Fungicide recommendations for stripe rust management have been based on disease threshold levels on specific leaves... Recent northern evaluation by QDPI&F, NSW DPI and NGA has confirmed that the most effective management of stripe rust will be achieved by spraying at or just prior to disease becoming evident in a crop...

Overall, wheat diseases have the potential to cause very significant costs for farmers... The estimates of potential losses assume that for each disease, it is the only one that develops... The drier seasons of the past decade (Section 3) would not favour these two diseases and is the likely cause of their reduction in importance...
