Episode 229: Stripper fronts – time saving, fuel saving and moisture saving

Farmers across the Western Region are using a variety of stubble strategies to protect soil moisture over summer and to protect those soils from harsh winds. Noel Keding has taken stubble strategies to the next level using a stripper front on his cereals. Noel has some experience using stripper fronts in both low and higher rainfall environments, so his experience may help other growers who are wondering whether stripper fronts might be an option. On this podcast Noel talks about the advantages of using stripper fronts in his experience including significantly greater harvest efficiency but also some of the challenges such as getting the crop germinated and out of the ground because of the extra shading from the straw. stripper fronts, Noel Keding, soil moisture, soil and nutrition, agronomy

Episode 228: Eroded top soil

Losing just one millimetre of topsoil in a wind erosion event can result in significant changes to soil fertility and cause yield losses in subsequent crops of up to six per cent. But there are some measures growers can take to protect their topsoil and reduce the impact of severe wind. In this podcast, Cropfacts consultant Harm van Rees, Agronomy Solutions director Sean Mason and South Australian Department of Primary Industries and Regions consultant Mary-Anne Young join in a discussion on dealing with the effects of wind erosion via ongoing soil management or tactics when multiple dry seasons have ruled out other options. eroded top soil, soil and nutrition, agronomy, wind erosion

Episode 225: Stubble management in a changing climate

Changing rainfall patterns in the drier parts of the western region have prompted a rethink of strategies for grower Clint Della Bosca. On this podcast focusing on stubble management in Western Australia, Clint talks about the vital importance of stubble in his system as weather patterns unfamiliar to his area begin to emerge. climate, Clint Della Bosca, grower stories, stubble management, soil and nutrition, agronomy

Episode 224: Plant available water capacity

Plant Available Water, is key to determining potential crop yield. It’s also the basis for sowing decisions and fertiliser applications. Many things affect how much stored soil water is available, rainfall before and during the growing season, infiltration, evaporation and transpiration. And then there’s Plant Available Water Capacity, which is the total amount of water a soil can store and release to a crop which differs depending on the crop. agronomy, soil and nutrition, plant available water capacity, Brett Cocks

Episode 223: Mouse management pre-sowing

As many Western and Southern region grain growers start preparations for sowing this year’s winter crops, there are still a few areas in the eastern states northern region where late sown summer crops such as sorghum are still standing. In this podcast you’ll hear from a leading authority on Mouse behaviour and management, about the challenges facing growers yet to harvest and those needing to plan a mouse baiting strategy pre-sowing. mouse management, pests, mouse, baiting, Steve Henry, crop protection

Episode 222: Barley Foliar Pathogens - The Global Search For Resistance (part 1)

Foliar diseases are a major constraint to profitable barley production across Australia, affecting both yield and quality. In this podcast, senior plant pathologist Dr. Lisle Snyman from the Department of Agriculture and Fisheries Queensland discusses the presence and spread of barley foliar pathogens across Australia's growing regions. Dr Snyman was part of the barley foliar pathogen project. The four-year GRDC investment successfully characterised major barley pathogens in Australia and identified effective resistance genes from around the world. Part two of this podcast focuses on a new three-year research initiative that is leveraging the findings from this completed research, by progressing the most promising NFNB, SFNB and scald resistance genes for use in Australian breeding programs. disease, foliar diseases, Dr. Lisle Snyman, barley, crop protection

Episode 221: Barley foliar pathogens - the global search for resistance (part 2)

New research is harnessing advanced computer capabilities and artificial intelligence to fast-track the development of new barley varieties with improved foliar pathogen resistance – shaving years off conventional breeding program processes. Dr Kai Voss-Fels is the project lead and senior research fellow with the Queensland Alliance for Agriculture and Food Innovation, based at the University of Queensland in Brisbane. The program is off to a strong start, thanks to the findings from the four-year barley foliar pathogen project. Part one of this podcast explores these findings in more detail, with focus on pathogen presence and spread across Australia’s growing regions.

Episode 220: INVITA – Innovations in plant testing in Australia

Growers are set to get better variety recommendations faster through a new GRDC investment, INVITA, which is adding value to the National Variety Trial (NVT) program. The investment is led by Prof Scott Chapman from the University of Queensland (UQ) which is working in collaboration with Australian partner, CSIRO. The investment, INVITA, leverages off a major EU investment INVITE (Innovations in plant Variety Testing in Europe), a consortium led by INRA in France (INRA being the French equivalent of CSIRO). The main INVITE collaborator with INVITA is Prof Fred van Eeuwijk, a statistician from Wageningen University and Research (WUR), the world's number one agricultural university. innovation, plant breeding, INVITA, Scott Chapman

Episode 219: Summer Weed Survey WA

Until now, only limited information has been available about in-paddock summer weed distribution and abundance in Western Australia. However, a two-year survey, which will be completed in 2021, will provide hard numbers for the entire wheatbelt. The survey, completed with investment from the GRDC, has been coordinated by Albany-based agronomist Andrew Storrie, of AGRONOMO. summer weed survey, weeds, crop protection, Andrew Storrie, Western Australia

Episode 217: The Social Dimension Of Insecticide Resistance And IPM

Australia’s ongoing reliance on a limited range of chemicals has set a concerning trajectory for insecticide resistance. Integrated pest management (IPM) strategies play an important role in curbing future resistance cases, however there’s a strong social dynamic at play when it comes to growers and advisers adopting these strategies on-farm. In this podcast, Bruce Howie from C-Qual Agritelligence and Kelly Angel from Birchip Cropping Group (BCG) delve into the social dynamic of IPM and share how advisers can help drive positive long-term change. This podcast has been developed as part of the investment, "Supporting the sustainable use of insecticides and local on-farm implementation of IPM strategies in the GRDC southern region”. The investment aims to provide knowledge and skills to growers so they are equipped with a range of appropriate IPM strategies for their situations. insecticide resistance, integrated pest management, Birchip Cropping Group, Bruce Howie, Kelly Angel, pests, crop protection
