Nutrient type and rate locations
Aims
  • To encourage Mark Stoeckel, Paringa-Murtho grain grower, to test a small range of nutrient and rate treatments on his paddock.
  • To use precision yield mapping to provide an accurate analysis of the trial.
  • To demonstrate Precision Agriculture technologies, especially variable rate to demonstrate reduced risk and maximised return in continuous cropping systems.
  • To show the benefits of using EM38 and 'Your Soils Potential' soil testing service to map subsoil constraints.
  • To demonstrate and extend the benefits of precision agriculture technology to SA Mallee growers.
Key messages

Variable rate fertiliser application has a real and profitable place in the Mallee when combined with good paddock science. The precision technology gives the ability to examine the yield data for many effects including other possible influencing factors such as elevation, slope aspect or orientation to the sun, and probably many others.
