  • Overcoming phosphorus stress in south-eastern Australia
    Soil and Nutrition, 28 Jan 2021
    Overcoming phosphorus stress in south-eastern Australia

    Phosphorus fertiliser is one of the most important and often limiting nutrients in agricultural production. A new project is testing the potential to improve crop nutrient uptake by dual banding phosphorus so it is co-located with moisture in the deeper soil layers.

  • Focus on legume crops’ nitrogen fixation in sandy soils
    Soil and Nutrition, 25 Jan 2021
    Focus on legume crops’ nitrogen fixation in sandy soils

    Growers with sandy soils could improve the ability of legume crops to fix nitrogen by addressing some factors unique to their soil type. Good nodulation is key to ensuring nitrogen fixation takes place; however, one South Australian agronomist and his team believe growers can make a few extra changes to enhance the nitrogen fixation process.

  • Annual legumes to build soil nitrogen for crops
    Soil and Nutrition, 20 Jan 2021
    Annual legumes to build soil nitrogen for crops

    Establishing vigorous legume pastures to boost nitrogen for the subsequent crop can be challenging in the mixed-farming regions of Australia, but will soon be simpler with new management techniques and improved annual hardseeded pasture legume species.

  • Optimum soil sampling strategies for the west
    Soil and Nutrition, 16 Jan 2021
    Optimum soil sampling strategies for the west

    The highly variable soils in Western Australia can be prone to over or under-fertilising, but a carefully considered sampling strategy can help resolve this.

  • GRDC boosts nutrient knowledge
    Soil and Nutrition, 15 Jan 2021
    GRDC boosts nutrient knowledge

    Together with using novel technologies to learn about soil function, a comprehensive approach is being taken by GRDC to upgrade current knowledge and practices to optimise nutrient use efficiency. This includes improving soil sampling, and learning more about fertiliser placement and soil nutrient cycling to inform upgraded fertiliser recommendations.

  • Cutting-edge technology to investigate root behaviour
    Soil and Nutrition, 14 Jan 2021
    Cutting-edge technology to investigate root behaviour

    The Australian Synchrotron has been enlisted to provide insights into plant root-soil relationships and better inform nutrient management decisions, particularly for constrained soils.

  • Deep-banding conundrum for deep-rooting traits
    Soil and Nutrition, 13 Jan 2021
    Deep-banding conundrum for deep-rooting traits

    Deep-rooting traits may help crops to access water, but with nutrients such as phosphorus and potassium concentrated in either the top few centimetres or in deep bands of fertiliser, how will these rooting traits affect the crop’s ability to access essential nutrients?

  • Pulse nitrogen boost for acid soils
    Soil and Nutrition, 10 Jan 2021
    Pulse nitrogen boost for acid soils

    A suite of improved rhizobia strains that are better adapted to acidic soils are being evaluated for release. Performance of the strains has been shown to be regionally specific and awareness is being raised of management practices that may affect rhizobia nodulation and activity.

  • Boosting deep-phosphorus availability in vertosols
    Soil and Nutrition, 22 Dec 2020
    Boosting deep-phosphorus availability in vertosols

    Deep-banded phosphorus provides a valuable supply of nutrition several years after application, but crop access is often limited by the supply of moisture in the band. Expanding the volume of fertilised soil may offer benefits, but success will depend on fertiliser–soil interactions in target soil types.

  • Big three nutrients under rigorous study
    Soil and Nutrition, 19 Dec 2020
    Big three nutrients under rigorous study

    The combined effects of changing farming practices and climate are driving the need to update nutrient management strategies for crop production in Western Australia. Innovative technologies and new insights into nutrient cycling are set to inform these improved strategies.
