    Managing waterlogging is a long road travelled

    Working with South Coast NRM on a GRDC-supported National Grower Network project, the Marold family has been evaluating the efficacy and economics of subsurface drains to increase the long-term sustainability of their production system. This has built on the family’s experience with raised beds, which were found wanting in the Esperance high-rainfall zone where waterlogging is a frequent event.

  • The continuing quest for a long-term waterlogging solution

    The continuing quest for a long-term waterlogging solution

    Waterlogging is a risk cropping in the high-rainfall Esperance region in Western Australia. To manage this risk the Marold family have been trialling several different forms of drainage.

  • Economics stack up for subsurface drains

    Economics stack up for subsurface drains

    A grower-led GRDC-supported project managed by South Coast NRM has investigated the efficacy and economics of installing subsurface drains in southern Western Australian cropping country prone to waterlogging.

  • Trials explore backup crop tactics after waterlogging

    Trials explore backup crop tactics after waterlogging

    The agility of GRDC’s National Grower Network enables it to quickly respond to seasonal events like waterlogging to provide valuable datasets and insights for grower’s decision-making. Trials in southern WA highlighted the importance of using short-season varieties and the timing of sowing after waterlogging, with economic analysis suggesting that losses can be minimised by swiftly establishing a late sown crop.

  • How well is fallow working to build profit across your farming system?

    How well is fallow working to build profit across your farming system?

    Waiting until there is a threshold of soil water before sowing is critical for maximising water use efficiency

  • New guide on water use for dryland cropping

    New guide on water use for dryland cropping

    The Grains Research and Development Corporation (GRDC) has introduced 'Water Smart Farming', a comprehensive manual designed to enhance water use efficiency in dryland cropping. This publication addresses the complex challenges of managing soil moisture, unpredictable rainfall, and varying soil and crop types. Aimed at growers and advisors, the manual consolidates the latest research into a single, accessible resource. Topics covered include crop water usage, plant available water capacity, technological advancements in water use efficiency, and managing dryland cropping risks. Mark Callow, GRDC’s sustainable cropping systems manager, emphasizes the importance of agronomic decisions rooted in up-to-date research for maximizing water efficiency and yield. Authored by leading Australian researchers, including CSIRO's Kirsten Verburg and SARDI's Peter Hayman, the manual presents an integrated approach to farm water management.

  • Comprehensive strategies to enhance western farming systems

    Comprehensive strategies to enhance western farming systems

    A series of major farming systems trials in Western Australia are taking a participatory approach in garnering baseline information to rethink aspects of cropping rotations. The data generated will be used by modellers to determine lower greenhouse gas emission cropping systems for growers in low and medium-rainfall regions.

  • Maize the winner, but it comes at a cost

    Maize the winner, but it comes at a cost

    Grain maize proved to be the highest-yielding irrigated crop in research trials but, as a summer crop, it also uses the most irrigation water.

  • Embracing a data-based approach to optimising soil moisture

    Embracing a data-based approach to optimising soil moisture

    Assessing the merits of using plant-available water capacity and soil moisture measurement are important parts of making on-farm decisions. Researchers agree that combining PAWC information with soil moisture monitoring can give growers an edge in decision-making, providing valuable information to help with decisions, including what and when to plant, the likely response to mid-season fertiliser applications, and yield predictions.

    The response to wet years

    Subsoil drainage, mitigation strategies, replacement crops and workshops were among the NGN-driven projects that tackled waterlogging impacts during the consecutive La Niña years
