James Walter is the bioinformatics lead at Australian Grain Technologies (AGT), working at the intersection of genetics, data science and plant breeding. His role focuses on turning vast amounts of genomic and field data into practical insights that help breeders make better decisions and ultimately deliver improved crop varieties to growers. In this episode, James takes us behind the scenes of the plant breeding pipeline, unpacking the journey from initial crosses in the glasshouse through to years of field trials, quality testing and eventual commercial release. He explains how modern breeding balances resilience and performance, why stability across seasons is critical, and how the explosion of data and new technologies is reshaping how varieties are developed. This episode explores: ● James’ pathway from agricultural science into bioinformatics and plant breeding ● What a role in genomics and data science looks like in agriculture ● How plant breeding programs work from glasshouse to commercial release ● Why it takes 8–10 years to develop a new crop variety ● The importance of stability versus peak performance in different seasons ● How genetics and field data are combined to guide breeding decisions ● The role of large-scale field trials across multiple environments ● How new technologies, AI and data are transforming plant breeding ● The sheer scale of data involved in modern breeding programs ● Career opportunities in agriculture beyond traditional farm roles Watch this episode as a video on YouTube: https://youtu.be/hEJmhVcDmtg More information: https://groundcover.grdc.com.au/innovation/climate/global-search-helps-heat-tolerance-gains-to-be-made-in-wheat https://www.agtbreeding.com.au/ GRDC in Conversation is a limited series GRDC Podcast.

In this episode of GRDC in Conversation, Oli Le Lievre sits down with Ashley Amourgis, General Manager of Southern Farming Systems, just west of Geelong. Growing up on a dairy farm near Deloraine in Tasmania, Ashley developed a deep appreciation for agriculture as a way of life. That grounding has shaped her journey into the grains industry, where she now works at the intersection of research, extension and farming systems in Victoria’s high rainfall zone. Ashley shares her pathway from university uncertainty and early rejection to nearly a decade in grains, reflecting on confidence, mentorship and stepping into leadership. The conversation explores nitrogen management in high rainfall environments, the importance of long-term Farming Systems research, the role of drainage in transforming southwest Victoria, and why every farm requires context rather than cookie cutter advice. Ashley also offers advice for young professionals entering agriculture and explains why, despite advances in AI and technology, people remain at the heart of the industry.

In this episode of GRDC In Conversation, host Oli Le Lievre sits down with Darcy Warren, a leading researcher at Field Applied Research (FAR) Australia based in Geelong. Darcy’s entry into agriculture was far from traditional; growing up in the leafy Melbourne suburb of Greensborough, he discovered agricultural science almost by accident at a university open day. From those early sparks of curiosity, Darcy has built a distinguished career, starting with a joint GRDC and Agriculture Victoria graduate program and progressing to help lead a national research team. The conversation explores the rapid growth of Field Applied Research (FAR) Australia from a small team of four to a national organisation. Darcy reflects on the "career-defining" Hyper Yielding Cereals project in Tasmania, the complexities of managing disease burdens, and the shifting landscape of fungicide resistance. Beyond the technical science, Darcy discusses the "people side" of agriculture—the importance of mentorship, the challenges of a travel-heavy career, and why he encourages the next generation of "city kids" to find their place in the grains sector.

What the eef are EEFs? This episode dives deep into not only what EEFs are, but how they can change modern grain farming. On the face of it, they are enhanced efficiency fertilisers, but what it can mean is farmers are able to take control over fertiliser loss in their paddocks and be a lot closer to meeting global emissions targets. A four year multi-million dollar co-investment is aiming to explore how Australian grain growers can improve nitrogen use efficiency and reduce on farm greenhouse gas emissions. In this podcast we speak to project lead, Dr Arjun Pandey from The University of Melbourne and also grower, Russell Zwar who has experience using EEFs.

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.
