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 Cameron Johnson as part of a GRDC series looking at managing soil constraints in Western Australia. Together, we talk about the process of renovating these tramlines to keep them flat and even, as well as the different machinery options to get the job done.

Much like mechanics might have cars in a less-than-ideal state, agronomists often have the messiest crops, with their attention going to their customers first. Kojonup grain farmer and agronomist Courtney Piesse isn’t too worried though, as his own agronomy business keeps the bills paid and his mind connected to the people and innovation alive in the industry.
In this episode of GRDC In Conversation, host Oli Le Lievre chats with Courtney about pivoting from his dream of being a fighter pilot to returning to ag, and his love of applying agronomy skills to care for different crops across the vast state of WA, from wheat in the Great Southern to irrigated horticulture in the far north.

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 podcast we hear from Dr Ali Bajwa, senior lecturer in weed science and agronomy at Melbourne's La Trobe University and South Australian grower Robin Schaefer on this episode.

Fritz Bolten is so dedicated to making agriculture work in Western Australia’s rugged Kimberley region he’s tried growing more than 26 different crops. He owns Oasis Farms, a 573 ha irrigated cropping enterprise in the Ord Valley growing chia, corn, chickpeas,
mungbeans, cotton and sorghum forage seed.
In this episode of GRDC In Conversation, host Oli Le Lievre chats with Fritz about why he’s transitioning to an exclusively cotton and corn rotation. His ‘have a go’ approach to farming has led to some big wins, but also some losses along the way, as he navigates the extreme monsoon weather conditions, logistical hurdles and limited infrastructure of the vast subtropical north.

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 effectively. The work is being led by CSIRO in collaboration with a network of research partners. To find out more, this podcast features project lead, CSIRO's Dr Mark Farrell, Dr Stirling Roberton, who is a research scientist, also at CSIRO, and from the University of Western Australia, Emeritus Professor Lynette Abbott.

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 part of a five-part GRDC series looking at managing soil constraints in Western Australia. Craig has three clients in the Eradu area, all aiming to achieve the same result, but doing it with different machinery and varied approaches.

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 Primary Industries and Regional Development in Western Australia, about what growers can do to help.
