    Ripper Gauge evaluates soil amelioration treatments

    A coordinated statewide project evaluating a suite of amelioration techniques on less-commonly ameliorated soil types in Western Australia is showing site-specific success and recommending growers should trial techniques before widescale application.

  • Northern trials probe moisture-seeking wheats
    Soil and Nutrition, 14 May 2021
    Northern trials probe moisture-seeking wheats

    The development of ‘long coleoptile’ genetics that allow wheat plants to establish on moisture deeper in the soil has attracted strong interest from grain growers.

  • Inoculation decisions made easy with new test
    Soil and Nutrition, 08 May 2021
    Inoculation decisions made easy with new test

    A new test that measures rhizobia numbers in the soil will help take the guesswork out of inoculation decisions for pulse growers in South Australia and Victoria. The PREDICTA rNod soil DNA test informs growers of the number of rhizobia in the soil and whether or not pulses might benefit from inoculation.

  • Know your soils before digging deep to overcome constraints
    Soil and Nutrition, 30 Apr 2021
    Know your soils before digging deep to overcome constraints

    Growers need to understand their soil constraints before considering deep ripping.

  • Paddock zones could boost P returns
    Soil and Nutrition, 27 Apr 2021
    Paddock zones could boost P returns

    With seeding ramping up across many parts of the southern region, growers are being reminded of the importance of monitoring and maintaining soil phosphorus levels in order to maximise yield and profit.

  • Study validates protein map-soil nitrogen link
    Soil and Nutrition, 26 Apr 2021
    Study validates protein map-soil nitrogen link

    A New South Wales study has assessed soil nitrogen variability across the landscape and demonstrated the value of protein maps as an indicator of plant-available nitrogen

  • 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.
