    Are potassium needs being met?

    Growers in the West Midlands region of Western Australia have identified potassium deficiency as a major issue affecting crop yields, leading to a GRDC National Grower Network-invested project to investigate and address this problem through detailed soil and plant testing.

  • Study evaluates carbon footprint of lime
    Soil and Nutrition, 01 Oct 2024
    Study evaluates carbon footprint of lime

    The research is part of a GRDC investment called Acid Soils Southern Region that aims to provide useful resources to help growers manage acid soils.

  • Amelioration begins the improved soils journey
    Soil and Nutrition, 16 Aug 2024
    Amelioration begins the improved soils journey

    Soil amelioration and continual soil improvement are enabling Jeremy Lush and his father Rodney to improve their farm's sustainability and diversity of crop rotation. He says the importance of providing adequate nutrition to his ameliorated soils is one of most valuable insights he has gained from amelioration research.

  • Double-break crop advantage explored
    Soil and Nutrition, 13 Aug 2024
    Double-break crop advantage explored

    With support from GRDC’s National Grower Network, a team of grower groups led by West Midlands Group has determined that double break crop sequences, such as early sown chickpeas, can yield increased profit as compared to canola-wheat sequences.

  • Amplifying the impact of amelioration
    Soil and Nutrition, 01 Aug 2024
    Amplifying the impact of amelioration

    With the benefits of soil amelioration generally understood, research is now showing how to maintain and build yield and soil health in the years that follow

  • Trials test ground cover strategies in Central Queensland
    Soil and Nutrition, 24 Jun 2024
    Trials test ground cover strategies in Central Queensland

    A grower-driven research project is exploring the viability of cover crops and other options for Central Queensland growers to increase ground cover levels.

  • Deep ripping and topsoil inclusion: a case study at paddock scale
    Soil and Nutrition, 19 Jun 2024
    Deep ripping and topsoil inclusion: a case study at paddock scale

    Case studies enable a detailed consideration of complex issues, and this is what Bindi Isbister and a team from the DPIRD have taken to a deep-ripped paddock near Geraldton. The aim was to examine plant performance down the ameliorated profile to give direction to future ripping operations.

  • Insights to inform water repellent soil management
    Soil and Nutrition, 18 Jun 2024
    Insights to inform water repellent soil management

    Professor David Henry and his team from Murdoch University are combining new capabilities in computational chemistry with conventional analytical chemistry to identify the compounds causing water repellency in Western Australian soils. This information will enable the development of targeted, novel soil amendments.

  • Strategies to maximise groundcover following deep tillage
    Soil and Nutrition, 12 Jun 2024
    Strategies to maximise groundcover following deep tillage

    Agronomic practices post strategic deep tillage are being refined by a team of Department of Primary Industries and Regional Development researchers across four port zones in Western Australia. The research points to the importance of the timing of the operation, choice of variety and seeding rates to maximise ground cover and minimise soil erosion loss.

  • Emerging new generation of nitrogen management tools
    Soil and Nutrition, 03 Jun 2024
    Emerging new generation of nitrogen management tools

    Commercialisation has begun on the outputs from the Future Farm initiative, which sought to deliver more-targeted, precise and profitable fertiliser decisions in near-automated processes that are more efficient for agronomists and growers
