Susanne leads a vibrant team researching natural ecosystems and agroecosystems focussed on plants, microbes and soil. This aims to advance the circular nutrient economy, the restoration of degraded soils and landscapes, and the sustainable use of Australia's flora.
Funded PhD and MPhil positions are available in the (i) Bushfood project and the (ii) Next-generation fertilisers project and soil ameliorants project. Honours and Masters projects are available in all active projects. Please register your interest emailing Susanne.Schmidt@uq.edu.au

Completed projects
Re-purposing nutrient-rich wastes enable the circular economy. Benefits are safe and autonomous fertiliser supply chains, lower costs for farmers, improved environmental outcomes, and new industries and jobs.
Re-carbonising soils and improving nutrient use and fertiliser efficiencies mitigate climate change and boost agricultural efficiency. Reducing greenhouse footprints by storing carbon in soils also benefits degraded soils and boosts agricultural production.
Advancing the Indigenous economy by enabling the sophisticated Knowledge of Australia's First Nations people to be implemented by the Traditional Owners has many benefits: safeguarding landscapes from wildfires, developing environmental markets for carbon and biodiversity protection, and harnessing the food potential of Australia's native flora.

Boosting soil carbon storage and nutrient efficiency
We can mitigate climate change and restore degraded soils by replenishing carbon in agricultural soils through re-purposing carbon- and nutrient-rich organic wastes. This transdisciplinary project has plant and soil scientists working alongside waste engineers, government and industry partners in the Industry Transformation Training Centre for Biosolids (www.transformingbiosolids.org.au). Candidates interested in researching biosolids - digested, heated or pyrolysed will identify safe and efficient ways for rebuilding soil carbon stores and delivering nutrients to plants.
Nature's littlest helpers: biocrusts boosting carbon and nitrogen of grazing lands
Cattle grazing of northern Australia's savannas has to support the industry's goal of carbon neutrality. Our project quantifies the benefits of biocrusts, the living cover of soil that consists of rich microbial communities that fix carbon and nitrogen, enhance soil fertility and prevent erosion. Spanning from molecular profiling of the smallest of organisms to remote sensing via satellite to track change over time, we address questions such as "What organisms live in biocrusts and what do they do? What management practices (grazing, fire) ensure landscape integrity and profitability?
Protecting rare rainforest plants from myrtle rust
Rare species in the Myrtaceae family occupy Queensland’s world-heritage listed Gondwanan rainforest. Many of these species are on the brink of extinction as myrtle rust is killing vulnerable species that are weakened by changing weather patterns. The protection status of the forest prevents the use of fungicides and alternatives are urgently sought. Since many of these plants naturally accumulate heavy metals, an intriguing idea is if these metals can fend off myrtle rust. Our interdisciplinary team of experts in plant pathology, ecophysiology, rare plant ecology and propagation will support students carrying out field and laboratory research to test the interactions between heavy metal accumulation and tolerance to myrtle rust. A scoping project at Honours level is available.

Boosting soil carbon storage and nutrient efficiency
We can mitigate climate change and restore degraded soils by replenishing carbon in agricultural soils through re-purposing carbon- and nutrient-rich organic wastes. This transdisciplinary project has plant and soil scientists working alongside waste engineers, government and industry partners in the Industry Transformation Training Centre for Biosolids (www.transformingbiosolids.org.au). Candidates interested in researching biosolids - digested, heated or pyrolysed will identify safe and efficient ways for rebuilding soil carbon stores and delivering nutrients to plants.
Nature's littlest helpers: biocrusts boosting carbon and nitrogen of grazing lands
Cattle grazing of northern Australia's savannas has to support the industry's goal of carbon neutrality. Our project quantifies the benefits of biocrusts, the living cover of soil that consists of rich microbial communities that fix carbon and nitrogen, enhance soil fertility and prevent erosion. Spanning from molecular profiling of the smallest of organisms to remote sensing via satellite to track change over time, we address questions such as "What organisms live in biocrusts and what do they do? What management practices (grazing, fire) ensure landscape integrity and profitability?
Protecting rare rainforest plants from myrtle rust
Rare species in the Myrtaceae family occupy Queensland’s world-heritage listed Gondwanan rainforest. Many of these species are on the brink of extinction as myrtle rust is killing vulnerable species that are weakened by changing weather patterns. The protection status of the forest prevents the use of fungicides and alternatives are urgently sought. Since many of these plants naturally accumulate heavy metals, an intriguing idea is if these metals can fend off myrtle rust. Our interdisciplinary team of experts in plant pathology, ecophysiology, rare plant ecology and propagation will support students carrying out field and laboratory research to test the interactions between heavy metal accumulation and tolerance to myrtle rust. A scoping project at Honours level is available.
Indigenous-led bushfood industry: production systems for native plants
This project forms part of the Indigenous-led Australian Research Council-funded project "A Deadly Solution: Towards an Indigenous-led bush food industry". Indigenous communities will take a lead in the ever-expanding bushfood industry to develop bushfood plants for horticulture and new food and flavour products. The project advances economic opportunities for Australia's Traditional Owners to achieve cultural, health and environmental benefits. Native plants, their propagation, and production systems are the focus, with the opportunity to link to business, food and social science. Projects for all levels are available.
War on Waste - turning food organics and green organics (FOGO) into superior fertilisers
Our team of plant and soil scientists, engineers and compost industry develops next-generation fertiliser derived from wastes, i.e., food organics/green organics (FOGO) and other recyclates. Currently, FOGO often ends up in landfill and generates greenhouse gases. 'Bioengineering' superior compost formulations will have numerous benefits - improving soil, boosting crop growth and benefiting farmers, consumers and the environment. The project is supported by the Fight Food Waste CRC (https://fightfoodwastecrc.com.au/) and the organic waste recycling industry.
Quantifying benefits from compost for sugarcane farming
Soil and crop health are integral to high crop yields, yet degraded soils that have lost physical, chemical and biological function often reduce crop vigour and yield. We want to understand how compost can improve soils and this project will test the changes in vital soil functions at an innovative sugarcane farm in NQLD that has been using compose for several years.
