GRDC Grower Forum – Maitland
22 September 2021 @ 10:30 am - 1:30 pm
Physical disturbance, including deep ripping, spading and inclusion ripping, is proving beneficial to close the yield gap in sandy soils. This work is part of a GRDC project underway across the Southern Region.
It’s among the insights that will be presented by CSIRO Principal Research Scientist Dr Therese McBeath at free GRDC Grower Forums in Maitland on September 22 and Melrose on September 23.
“Physical disturbance helped close the yield gap at half of the 20 sites analysed, including Bute, Kybunga and Warnertown,” she said.
“For example, all sites which targeted physical soil constraints, and didn’t have significant repellence or subsoil toxicities, demonstrated positive first-year responses to deep ripping ranging from 0.2 t/ha to 1.2 t/ha.”
Dr McBeath will also give an update on the calcareous soils project, which is working to understand profit restraints on highly calcareous soils in the Southern Region. She will share preliminary results from field and laboratory experiments on a range of chemical and biological treatments aimed at boosting productivity.
GRDC Grower Relations Managers Randall Wilksch and Tom Blake will provide insights into current research and extension projects which address locally identified issues.
The Grower Forums also provide an opportunity to contribute your suggestions for future GRDC investment in research, development, and extension and to talk to GRDC representatives.
Please bring your laptop or tablet for use during the workshop session. Devices will also be provided. Light refreshments provided
