Summit Collaboration

Each year Summit conducts more than 30 field trials across the farming areas of Western Australia.

In 2018 we have been part of an ongoing research project, funded by the GRDC, looking at the major nutrients, Nitrogen, Phosphorus and Potassium.

The project is titled “Increasing profit from N, P and K fertiliser inputs into the evolving cropping sequences in the Western Regionand aims to provide clarity to critical soil analysis values and recommendations for a number of crops.


Summit’s role in this project is to provide Phosphorus trials, and some potassium trials as well.

This is a large project with Summit’s role in 2018 being 6 trials located at


  • Northern Ag Group – Binnu
  • Mingenew
  • Williams
  • Merredin
  • Yealering


  • East Ballidu

The results of these trials will add to the pool of data that Summit has amassed from our over 25 years of field research in Western Australia.
