  • Sensor helps untangle sorghum’s complicated water use interactions
    Sensor helps untangle sorghum’s complicated water use interactions
    Issue 158, May-June 2022 - 22 May 2022

    Although sowing sorghum in winter helps avoid stress at sensitive crop stages, little is known about root growth and function in cold soils, or how genotype and management combinations affect root growth and water use. A sensor is helping to fill in those gaps

  • Prize to test novel frost intervention feasibility
    Prize to test novel frost intervention feasibility
    Issue 158, May-June 2022 - 13 May 2022

    Mitigating frost in cropping systems is complex, but there may be a new tool available in the future through some creative thinking on behalf of two young scientists. Jaco Zandberg and Samantha Harvie from the University of Western Australia are investigating a novel way to disrupt the action of ice nucleating bacteria. The proof-of-concept study is being supported by a Federal Government’s Department of Agriculture, Water and the Environment 2022 Science and Innovation Award won by Mr Zandberg and provided by GRDC.

  • Frost physiology knowledge base grows

    Issue 158, May-June 2022 - 11 May 2022

    GRDC takes a multi-pronged approach to supporting Australian growers in the crop production decisions they make. Training scientists for the future is key to its capacity building agenda and an example is Mr Brenton Leske, who since completing his PhD at the University of Western Australia, embedded in the GRDC’s former National Frost Initiative investment and supported through DPIRD’s postgraduate scholarship program, has now returned to DPIRD to co-lead the frost research, developing frost management knowledge and tools for growers.

  • Innovators turn straw into renewable ammonia
