Honorary Professor Susanne Schmidt

Researcher biography
Susanne Schmidt specialises in plant–soil–microbe interactions and ecosystem biogeochemistry. Research of her team has advanced understanding of nitrogen, carbon and phosphorus cycling in both natural and agricultural ecosystems, uncovering fundamental mechanisms that govern nutrient cycling from cellular to ecosystem scales. This work has challenged long-held paradigms in plant nutrition and provides scientific foundations for sustainable agriculture and resource management.
The discovery that plants are mixotrophic and can access complex organic compounds has reshaped concepts of plant nutrition, with implications for next-generation fertilisers, soil carbon sequestration and nutrient recovery from waste streams. This supports the transition to a circular nutrient economy, contribute to climate change mitigation, and strengthen Indigenous-led initiatives safeguarding Australian ecosystems and plants.
