Benefits, Barriers and Opportunities for Precision Ag in Australia

6000Ha

Precision Ag on our properties must:

• Increase profitability • Make my life easier


• The easiest PA is the most effective • The biggest barrier to adoption is intentional incompatibility • Go “G Rated” (Generic):

• Cheaper • Better • Easier


Poor man’s PA

The Bottom Line

• PA can be as simple as using different rates in different paddocks

• The BIGGEST PROFITS from PA are from matching inputs to the TRUE yield potential

• Use “G Rated” Generic technology to get there sooner

• PA is about grabbing all the 1’s and 2’s. Make sure you have the 10’s and 20’s sorted first

• Adding the benefits of PA to a well managed program leads to substantial profits

• A blanket rate is still better than the right rate in the wrong place

The most important thing is to start

• Save screenshot/photo in Dropbox • Use “Paint” to crop image on computer • Duplicate the file, change “.png” to “.pwg”

– (or .jpg->.jwg, .bmp->.bwp etc) • Compress both files into one .zip folder • Open zip folder in iPad using Dropbox App • “Open in...” GISKit • Georeference 3 or more points in image against Google image • Easy!!
