NUE Lab_Susanne-Schmidt

Prof. Susanne Schmidt

Susanne’s passion for plant nutrition has resulted in a diverse research portfolio at the intersect of agriculture and ecology. Her research focusses on tropical plants, soils and microbes – from fundamental to applied.

As an educator, she coordinates and teaches undergraduate courses in plant science and ecology. Students graduating from her team work in industry, academia and government.

Dr. Nicole Robinson

Nicole’s research interests span natural and agricultural systems dissecting how plants, microbes and soils interact with the aim for improved nutrient use efficiency to maximise production and reduce off-site environmental impacts.

A major research focus has been characterising nitrogen use efficiency in sugarcane across broad germplasm and the impact of nitrogen source availability and plant nitrogen use.

Current projects with sugar and cotton industry focus on soil health and nutrient cycling and the impact of crop management and resultant effects on productivity and stability of yield.

Ph.D. Students

Lemuel Precados

Lemuel Precados

Ph.D. Student

Lemuel’s project involves measuring relative technical efficiency and total factor productivity in rice cultivation in the Philippines using data envelopment analysis. Lemuel aims is to work out cost-saving potentials for an efficient utilization of critical input resources for smallholders in the Philippines and its associated implications for reducing environmental pollution.

Taleta Bailey

Taleta Bailey

Ph.D. Student

Taleta’s research centres around improving management of nitrogen in agricultural systems. I have a growing interest in the role of soil carbon for linking plant and microbial processes, sustaining productivity and mitigating environmental impacts. My PhD focuses on the interactions between carbon and nitrogen cycling in soils and using a better understanding of nitrogen transformations between organic and inorganic forms to improve fertiliser use.

Anoma Ranagalage

Anoma Ranagalage

Ph.D. Student

Anoma’s research focuses on evaluating genotypic variation for biomass accumulation, N accumulation and (Nitrogen Use Efficiency)NUE over the sugarcane crop cycle in response to N supply. Moreover, underpinning physiological and agronomic traits associate with NUE and the dynamics of the traits in sugarcane crop classes also focused as other key aspects.

Michael Walsh

Michael Walsh

Ph.D. Student

Michael’s research centres around improving the sustainability and sovereignty of Australia’s agricultural industry through the understanding and use of recycling waste into fertilisers. Michael’s Ph.D. involves analysing novel recycled-based fertilisers and how they can be improved as a fertiliser.

Mary Addae

Mary Addae

Ph.D. Student

Mary’s research focuses on the cost-benefit analysis and environmental impact assessment of composting food and organic waste to turn Australia’s food waste problem into gains. The study aims to analyse the economic feasibility and assess the potential environmental impact to optimise the benefits of converting Australia’s food and organic waste into compost, specifically ‘smart compost formulations’ that are optimised for specific crops and biophysical conditions.

Rhys Pirie

Rhys Pirie

Graduation pending

Rhys’ research focused on turning ‘waste’ glass into sodium silicate, a valuable industrial feedstock used in the manufacture of thousands of consumer goods. Further research has explored new uses for the end-products; assuming a step-change decrease in production costs. Research areas include: supply chain analysis, chemical engineering, soil science and plant nutrition.
