  • Annual legumes to build soil nitrogen for crops
    Annual legumes to build soil nitrogen for crops
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 20 Jan 2021

    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
    Optimum soil sampling strategies for the west
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 16 Jan 2021

    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
    GRDC boosts nutrient knowledge
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 15 Jan 2021

    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
    Cutting-edge technology to investigate root behaviour
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 14 Jan 2021

    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
    Deep-banding conundrum for deep-rooting traits
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 13 Jan 2021

    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
    Pulse nitrogen boost for acid soils
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 10 Jan 2021

    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
    Boosting deep-phosphorus availability in vertosols
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 22 Dec 2020

    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
    Big three nutrients under rigorous study
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 19 Dec 2020

    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.

  • Fertiliser band dynamics affect nutrient recovery
    Fertiliser band dynamics affect nutrient recovery
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 14 Dec 2020

    Increasing the rate of phosphorus fertiliser in deep banding can deliver agronomic benefits, but may also reduce the efficiency of nutrient recovery by crops. A University of Queensland study is investigating the impact of chemical changes in the band environment.

  • Probe into ironstone gravel soils
    Probe into ironstone gravel soils
    Supplement: Nutrient management for enduring profitability, January-February 2021 - 10 Dec 2020

    The nutrient dynamics of ironstone gravel soils of southern Australia are being unravelled with cutting-edge equipment to provide insights for better-informed management.
