Are bacteria a part of the frost puzzle?
Frost is a complex constraint on crop production, inflicted primarily by severe weather conditions, but a new look is being taken using state-of-the art techniques at the potential role of ice nucleating bacteria. If research can confirm the part these bacteria may play it may provide new tools for growers to manage frost.

Prize to test novel frost intervention feasibility
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
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.

Trials assess soil nitrogen carryover after frost or heat
A new research project is underway to give Western Australian growers a better understanding of the conditions and soil types under which nitrogen is carried over from one season to the next.

Peer-to-peer frost learning focuses on risk zones
Frost is a complex cropping constraint to manage but growers have benefited from sharing their experiences through pre-seeding workshops in Western Australia. The major focus was on zoning paddocks according to their frost risk and managing them accordingly.

Paddock maps track Jack Frost
A new model-based system developed by CSIRO researchers enables growers to map frost movement over paddocks. Minimum temperature maps of paddocks offer the chance to bring damaging frost episodes into clearer focus on a farm scale.

Oats to be supercharged as GRDC ups the ante
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.

Structure seeding programs to minimise frost risk
ConsultAg consultant Garren Knell cautioned growers not to enter the 2021 cropping season with a false sense of security about frost after experiencing minimal frost damage in 2020.
