    Making better use of your lime budget

    Applying enough lime to manage acidity in a smaller area has advantages over applying low lime rates across more hectares. The longer-term effect from using a higher lime rate as part of a ‘treat it properly’ strategy is higher yields for longer and better cash flow.

  • Clay soil amelioration shows promising results
    Soil and Nutrition, 30 May 2023
    Clay soil amelioration shows promising results

    Results from a trial incorporation of organic amendments into clay soils will see further research undertaken across commercial growing environments in Gippsland. Yield results demonstrated improved worm populations in the topsoil and increased pasture dry matter yield across three plots where subsoil organic amendments were added.

  • Case studies show the value of proactive soil protection
    Soil and Nutrition, 25 May 2023
    Case studies show the value of proactive soil protection

    Practical tactics to protect soils from wind erosion using ground cover are being packaged and distributed through a series of on-farm case studies

  • Fertilising the system, not just the crop, can build soil organic matter
    Soil and Nutrition, 24 May 2023
    Fertilising the system, not just the crop, can build soil organic matter

    The frustration of seeing no change in soil carbon after 20 years of stubble retention prompted one CSIRO scientist to ask ‘Why?’

  • Trials to fine-tune canola-on-cereal stubble strategy
    Soil and Nutrition, 17 May 2023
    Trials to fine-tune canola-on-cereal stubble strategy

    A new project is examining issues around canola establishment into high cereal stubble loads in the Wimmera, Victoria

  • Stripper-disc systems in the high-rainfall zones
    Soil and Nutrition, 12 May 2023
    Stripper-disc systems in the high-rainfall zones

    High stubble loads in the high-rainfall zones have proven challenging for the adoption of stripper-disc systems

  • Computer model helps clarify taller stubble impacts
    Soil and Nutrition, 11 May 2023
    Computer model helps clarify taller stubble impacts

    Computer simulations are being run to extrapolate likely impacts on a farming system’s soil–water balance arising from taller stubble produced by stripper headers

  • Stubble height trials
    Soil and Nutrition, 10 May 2023
    Stubble height trials

    Growers have participated in trials to better understand the impacts of taller stubble on soil–water dynamics

  • What we know and what we need to learn about stubble retention
    Soil and Nutrition, 09 May 2023
    What we know and what we need to learn about stubble retention

    Information relating to stubble management has been collected and curated to identify knowledge gaps to more fully realise the benefits of stubble retention while avoiding potential downsides

  • Can you bank nitrogen in Western Australian soils?
    Soil and Nutrition, 05 May 2023
    Can you bank nitrogen in Western Australian soils?

    Working with 20 growers from GRDC’s National Grower Network, Dr Darren Hughes from Laconik has been investigating the nitrogen banking capacity of Western Australian soils following frosted crops. Unfortunately, it is not a source of nitrogen to be relied upon.
