PhD (Queensland University of Technology)
Professor David Rowlings is a soil scientist in the Sustainable Agriculture program at the Centre for Agriculture and Bioeconomy. His research sits at the nexus of the environmental and agricultural science, enabling high impact research outcomes that benefit both fields for positive global change and food security. He specializes in the development and utilization of improved sensing and monitoring technologies for mitigating environmental greenhouse gases, improving crop fertiliser-use efficiency and monitoring soil carbon, reactive nitrogen and biogeochemical processes. His work spans the Australian beef, dairy, grains, sugar and horticulture industries and he has worked internationally in cropping and rice systems.

- Soil carbon and nitrogen cycling
- Reactive nitrogen, biogeochemical cycles, nitrogen use efficiency
- Subtropical and semi-arid tropical farming systems
- Utilising organic amendments for sustainable agriculture and soil health
- Dryland cropping, improved pastures and dairy farming systems
- Carbon neutral beef
