    Research questions the value of applied N in mungbeans

    Mungbean crops typically require N to maximise yield, but recent research has found that mungbean crops will not respond to applied N fertiliser under a wide range of field conditions.

  • Yardstick projects provide feedback on nutrition
    Soil and Nutrition, 12 Mar 2021
    Yardstick projects provide feedback on nutrition

    Demonstration sites over two seasons across Western Australia have shown that little consistent evidence that crop varieties respond differently to nutrition strategies. However, results were highly variable and season and location specific highlighting the importance for growers to consider adjusting their fertiliser strategy throughout the year to increase yield or improve grain quality, and ensure inputs are not wasted by the crop.

  • Consider fertiliser type and placement to prevent toxic burn
    Soil and Nutrition, 10 Mar 2021
    Consider fertiliser type and placement to prevent toxic burn

    University of Adelaide PhD student Jacinta Dockerill is challenging the salt index approach which relates a fertiliser’s toxicity risk with its impact on salinity measured in a laboratory.

  • Know your soils before digging deep to overcome constraints
    Soil and Nutrition, 06 Mar 2021
    Know your soils before digging deep to overcome constraints

    GRDC has released new fact sheets on ‘Correcting layers of high soil strength with deep tillage’.

  • Pulse crop nitrogen fixation explained in free workshop series
    Soil and Nutrition, 23 Feb 2021
    Pulse crop nitrogen fixation explained in free workshop series

    Growers who attend the free technical workshops will also take part in an interactive session to learn how to conduct nodulation assessments using supplied plant samples.

  • 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.
