Catalogue: GRDC Final Reports
Precision Agriculture (PA) techniques were used to improve soilborne disease management... Disease inoculum levels were measured in zones of 20 paddocks, using sampling methodologies developed in GRDC/SARDI project DAS311... Zones were constructed using a range of spatial paddock data including satellite imagery (Normalised Difference Vegetation Index- NDVI), yield, ECa (from EM38), and elevation...

The maps can be used to assess how much variation is needed for PA to be profitable and identify areas of paddocks responsive to inputs... While the results will go some way towards informing the debate about the profitability of PA, it illustrates that the use of, and benefits from, PA technology vary from farm to farm - in line with farmer preferences and circumstances... A new approach to thinking about management zones as responsive/unresponsive to inputs, rather than the traditional approach of static zones based on average yield performance...
