Cultivating learning: Ag education for Aussie kids

According to a survey done by the Primary Industries Education Foundation Australia (PIEFA), 75 per cent of surveyed students say they know nothing or little about the grains industry - despite it being one of Australia’s largest exports. In this episode, PIEFA CEO Luciano Mesiti outlines one of their key aims; to increase student knowledge and understanding through boosting teachers’ confidence with agricultural content. This is a concept shared by GRDC and reflected in their long-term relation...

A practical guide to tramline renovation machines

Permanent tramlines in a controlled-traffic farming system offer a range of benefits including less soil compaction across the whole paddock, fuel savings, higher yields and better in-crop access. Over time, tramlines can compact deeper than the rest of the paddock and can become rutted, with ridges forming where tyres push soil to the sides of the tramline. In this episode, we’re joined by Bindi Isbister from the Department of Primary Industries and Regional Development (DPIRD) and grower Camer...

Updates on Gazania control

Vibrant, colourful blooms and an attractive daisy-like appearance make them a popular choice for gardens and landscaping. But unfortunately, quick growing gazanias are actually a weed, one that's jumped the fence and is now invading the paddocks of grain growers. GRDC has identified gazania as a weed threat and is responding by investing in research to determine its distribution and abundance, review current control methods, and inform management strategies for the grains industry. In this podca...

Soil health in Australia

No matter what crop you grow, or livestock you run, the soil beneath your boots is the foundation of your farm's productivity, profitability, and long-term sustainability. And while soil has always been a cornerstone for grain growers, there's never been a consistent way to define, measure, monitor, or report on soil health in Australia. That's why GRDC has invested in the development of a national Soil Health Framework to close this gap and give growers the tools they need to manage soil more e...

Different angles on re-ripping: There is no right or wrong

Growers around the Eradu area of Western Australia's northern growing region have been deep ripping for many years. Now they're going back and re-ripping for a second, third, fourth, and even fifth time with different machinery as it has progressed over the years. It's all about getting highly alkaline surface soil down deeper in the profile to address subsoil acidity, and at the same time, managing compaction to greater depths. This episode features Craig Topham from Agrarian Management and is ...

Managing WPM fungicide resistance in the west

Fungicide resistance is a serious threat to cropping. When all available registered fungicides are no longer effective at managing disease, options for widespread disease control become limited, and the result is high yield losses. So, when a gateway mutation, the first step toward fungicide resistance in wheat powdery mildew (WPM), was detected in samples collected in Western Australia, alarm bells went off. In this episode we speak to Andrea Hills, research scientist with the Department of Pri...
