Trials 2016

2016 was a good season over most of Western Australia. Good seasons put pressure on soil nutrient supply, making results from Field Trials more relevant. Summit conducted trials across the state, looking at all the important nutrients and interactions. Once again the results are interesting and of great use to farmers. Please contact your local Summit Fertilizers Area Manager if you have any queries about the trials.
