Summit Fertilizers uses an independent laboratory for both soil & plant analysis with interpretations based on Agriculture WA data and our own extensive field research.

Some fertilizer can be coated with IMPACT® or Endure to help control Blackleg in Canola and some cereal diseases. Get over the phone or on the farm advice through Summit's own agronomists or our extensive network of agents.

Summit carry out a range of field trials every year, the results of which can be found here. Custom blending is a Summit specialty.
