  • Protein maps help define nitrogen needs
    Soil and Nutrition, 11 Apr 2021
    Protein maps help define nitrogen needs

    A New South Wales grain growing family is using wheat grain protein maps to indicate areas of paddocks that need more urea to lift yield

  • Soil testing guides optimal crop nutrition and stubble production to reduce erosion risks
    Soil and Nutrition, 08 Apr 2021
    Soil testing guides optimal crop nutrition and stubble production to reduce erosion risks

    Agronomists in the South Australian and Victorian Mallee say that using soil testing to optimise crop biomass and soil nutrition decisions can help avoid topsoil erosion and yield losses. Research shows that losing one millimetre of topsoil can result in yield losses of between one and six per cent.

  • Modern agronomy opens door to nitrogen rethink
    Soil and Nutrition, 31 Mar 2021
    Modern agronomy opens door to nitrogen rethink

    Leading crop researcher Dr James Hunt is exploring a new concept called the nitrogen bank, with promising early results

  • Long-term no-till trial delivers data legacy
    Soil and Nutrition, 24 Mar 2021
    Long-term no-till trial delivers data legacy

    A long-term trial undertaken by the Western Australian No-Tillage Farmers Association has not only provided significant insights for growers into the principles of conservation agriculture practices, but also added to the international science base and trained future systems-thinking scientists.

  • Research questions the value of applied N in mungbeans
    Soil and Nutrition, 16 Mar 2021
    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.
