Nitrogen application and NDVI locations
Aims
  • To encourage Bruce and Robert Pocock, to test a the applicability for NDVI mapping for making nitrogen application decisions on their paddock, and to use precision yield mapping to provide an accurate analysis of the trial. 
  • To demonstrate NDVI technologies to demonstrate reduced risk and maximised return for Nitrogen application in the Mallee.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

The objective of this GRDC / SPAA funded project is to increase the level of adoption of PA 'beyond guidance' by broadacre farmers. The project specifically aims to increase the level of adoption of variable rate (VR) by growers in the project to 30% by 2013.This goal will be achieved by demonstrating how to use PA tools to growers at a regional level and by increasing the skills of growers and industry in PA to a level where they can then use PA tools in their farming systems to achieve economic, environmental and social benefits.
