    Forecasts fortified for decision-making confidence
    Author: Dr Sue Knights, 18 Jun 2021

    Comparative report cards for international climate models will provide agriculturally relevant comparisons of their effectiveness to forecast for agricultural metrics. And new Bureau of Meteorology products are being test-driven by growers to help make more-informed climate-related decisions.

  • Potassium intrigue after sandy soils amelioration
    Potassium intrigue after sandy soils amelioration
    Author: Dr Sue Knights, 27 May 2021

    Amelioration of Western Australia’s sandy soils is showing that the practice can improve potassium availability and points to the need for further changes in potassium management practices to improve crop yields.

  • School still in for residue management
    School still in for residue management
    Author: Dr Sue Knights, 20 May 2021

    Crop residue management is vital in water-limited and erosion-prone cropping environments where no-till has become an important part of cropping practices. The Western Australian No-Tillage Farmers Association long-term trial has amassed 12 years of data, which is now providing valuable insights to improve residue management.

    Author: Dr Sue Knights, 19 May 2021

    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.

  • New residue management practice delivers
    New residue management practice delivers
    Author: Dr Sue Knights, 15 May 2021

    Cropping in the higher rainfall regions of Western Australia brings its challenges in respect to residue management, but the Heggatons near Kojonup are fine-tuning their practice with many benefits including improved water use efficiency.

  • New tool aligns climate models with on-farm decision making
    New tool aligns climate models with on-farm decision making
    Author: Dr Sue Knights, 27 Mar 2021

    The AgScore project puts different seasonal climate systems under the microscope to better understand which models might offer skilful forecasts up to six months into the future. The project asks ‘How good is the forecast?’ not just in terms of rainfall, but the potential to use the model data to forecast yield and other productivity metrics related to on-farm decision making.

  • Long-term no-till trial delivers data legacy
    Long-term no-till trial delivers data legacy
    Author: Dr Sue Knights, 24 Mar 2021

    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.

  • Oats to be supercharged as GRDC ups the ante
    Oats to be supercharged as GRDC ups the ante
    Author: Dr Sue Knights, 17 Mar 2021

    As Gary Lang’s highest profit earner and with reasonable frost resistance, oats have become a regular part of his cropping rotation at Wickepin in Western Australia. This drives Gary’s keen interest in GRDC’s announcement of a comprehensive boost to oat improvement.

  • Yardstick projects provide feedback on nutrition
    Yardstick projects provide feedback on nutrition
    Author: Dr Sue Knights, 12 Mar 2021

    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.

  • Optimum soil sampling strategies for the west
    Optimum soil sampling strategies for the west
    Author: Dr Sue Knights, 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.
