BIO – After completing my PhD, I moved back to Adelaide to take up an exciting role at Adelaide University’s Waite campus where an opportunity had come up to explore the impact of undervine cover crops on winegrapes. Under the mentorship of Chris Penfold and Prof Tim Cavagnaro, I studied two mature field trials, comparing a variety of cover crops in the Barossa Valley and Langhorne Creek wine regions of South Australia. We collected data on the cover crop’s impact on vine physiology, soil health, microbiomes and wine quality. I was also able to establish two new field trials in the Limestone Coast, exploring non-chemical weed-control options including mulching and mechanical weeding. The cover crop work was then extended the Riverland where extreme heat, extreme irrigation rates and extreme yields are the norm. In 2022 I organised and chaired a workshop at AWITC (the Australian Wine Technical Conference) on undervine cover cropping.
Since then I have continued research into sustainable soil management, turning to almonds, where effects are much slower to accumulate in the soil. Though I am still passionate about viticulture work and enjoy any opportunity to speak about vineyard soil.
