Seasonally relevant information at your fingertips

ExtensionAUS™ brings together the experts into ‘communities of practice’ in crop nutrition and field crop diseases.

ExtensionAUS™ communities have members from state government, private industry, universities, industry organisations, grower groups and agronomists.

These experts meet monthly to discuss current issues, local insights and the knowledge around them, to determine where the gaps lie and respond to what’s front of mind for growers and advisers in their area of expertise. This regular interaction helps inform decision making and allows extensionAUS™ to deliver real-time, quick and easy access to information; equalling faster and better-informed decision-making. Our experts peer-review all information published by extensionAUS™, ensuring extensionAUS™ is not only timely and relevant but research-based and credible.
