    Evidence from trials and growers suggests ripping non-dispersive duplex soils can help reduce waterlogging.

  • Call to redefine soil constraints
    Soil and Nutrition, 06 Jul 2021
    Call to redefine soil constraints

    Referring to physically dispersive soils as sodic soils is leading to ineffective and uneconomical testing and management strategies

  • Ripper idea to engineer soil fix
    Soil and Nutrition, 02 Jul 2021
    Ripper idea to engineer soil fix

    Dreaming big, researchers and a machinery manufacturer have developed a ripper that can ameliorate soils at depth, an important part of a transformational soils project

  • Nowcasting plant-available soil water
    Soil and Nutrition, 17 Jun 2021
    Nowcasting plant-available soil water

    Improved plant-available water predictions are being developed using scaleable, modular modelling frameworks that can be put into use in new products by commercial third parties to assist growers in making more informed cropping decisions.

  • Managing canopy growth in higher rainfall zones to maximise yield
    Soil and Nutrition, 14 Jun 2021
    Managing canopy growth in higher rainfall zones to maximise yield

    Canopy management is essential for optimising water use and realising water limited potential.

    Protect soils and yields with advice from expert panel

    The podcast discusses findings from ‘using soil and plant testing data to better inform nutrient management and optimise fertiliser investments for grain growers in the southern region.’

  • Potassium intrigue after sandy soils amelioration
    Soil and Nutrition, 27 May 2021
    Potassium intrigue after sandy soils amelioration

    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.

  • Review explores options to lift returns on sodic dispersive subsoil
    Soil and Nutrition, 24 May 2021
    Review explores options to lift returns on sodic dispersive subsoil

    With experiments showing amelioration of sodic subsoils could lift grain yields by 20 to 53 per cent, independent consultants Peter and Hazel McInerney of 3D-Ag reviewed what could be achieved on similarly responsive sodic soils

  • School still in for residue management
    Soil and Nutrition, 20 May 2021
    School still in for residue management

    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.

  • New research into cost of improving farming country
