Root effects on soil organic matter: a double-edged sword. This project aims to understand how plant roots build and destroy soil organic matter in grasslands and what the impacts are of drought. Soil organic matter is the largest terrestrial reservoir of nutrients for plant growth, but paradoxically, formation of new soil organic matter by plant roots also requires external nutrients. This project will address this apparent paradox by using a new root-centric framework and stable isotope techni ....Root effects on soil organic matter: a double-edged sword. This project aims to understand how plant roots build and destroy soil organic matter in grasslands and what the impacts are of drought. Soil organic matter is the largest terrestrial reservoir of nutrients for plant growth, but paradoxically, formation of new soil organic matter by plant roots also requires external nutrients. This project will address this apparent paradox by using a new root-centric framework and stable isotope techniques. The project will use state-of-the art computer models that incorporate the latest frameworks on soil organic matter interacting with plant roots. Benefits include an improved capacity to manage and predict grassland productivity and soil organic matter dynamics with greater resolution and accuracy.Read moreRead less
Role of nitrogen-rich compounds for increasing carbon sequestration in soil. This project aims to unravel how increasing concentrations of nitrogen-rich compounds in soils can potentially increase our ability to sequester soil organic carbon. This is significant because long-term agricultural production greatly reduces soil organic carbon stocks and releases carbon dioxide as a greenhouse gas. Expected outcomes of this project include providing information that is urgently needed to develop pred ....Role of nitrogen-rich compounds for increasing carbon sequestration in soil. This project aims to unravel how increasing concentrations of nitrogen-rich compounds in soils can potentially increase our ability to sequester soil organic carbon. This is significant because long-term agricultural production greatly reduces soil organic carbon stocks and releases carbon dioxide as a greenhouse gas. Expected outcomes of this project include providing information that is urgently needed to develop predictive carbon models for effective policy-making and improved management. This project should provide substantial benefits, including fulfilling the carbon sequestration potential of Australia’s soils, thereby delivering positive economic outcomes through increased farm-gate output and mitigation of climate change.Read moreRead less

Upcycling tailings into soil (technosols developed from technogenic parent materials) offers a sustainable approach to overcome severe topsoil shortage that limits the progress of ecological rehabilitation of tailings across mine sites. This project aims to establish new knowledge on mineral bioweathering, organic carbon (OC) sequestration in rapidly formed mineral phases, and OC turnover driven by colonising microbes and plant roots, in the early pedogenesis of tailings initiated by inputs of organic and inorganic materials. This new knowledge is required for developing eco-engineering technology adaptable to a wide range of tailings of diverse mineralogy, to achieve sustainable tailings rehabilitation and organic carbon sequestration.Read moreRead less

Defining and engineering the rhizosphere for Australian rainfall patterns. The manner in which plants use carbon and water defines agricultural and natural landscapes. Today's models that predict plant improvement rely on carbon and water usage by plant leaves. However, the first interaction between plants, carbon and water occurs in the rhizosphere; a diverse zone with dynamic root-microbiome interactions. We will use advanced visualisation and mathematics to determine fine scale relationships ....Defining and engineering the rhizosphere for Australian rainfall patterns. The manner in which plants use carbon and water defines agricultural and natural landscapes. Today's models that predict plant improvement rely on carbon and water usage by plant leaves. However, the first interaction between plants, carbon and water occurs in the rhizosphere; a diverse zone with dynamic root-microbiome interactions. We will use advanced visualisation and mathematics to determine fine scale relationships between microbes and roots in the rhizosphere when exposed to water levels reflective of current and projected rainfall values. From generated knowledge of water and carbon dynamics caused by intimate microbe-root interactions, we will provide water saving, soil regeneration and improved carbon biosequestration strategies.Read moreRead less
Linking soil acidification with carbon dynamics in Australian agroecosystems. The ability to mitigate climate change by sequestering soil carbon may be limited in acidic soils, which are prevalent in Australia. The project will investigate the link between carbon cycling, soil acidification and liming, and provide important knowledge to identify agricultural practices which have the capacity to build soil carbon.
Tandem Photocatalytic Conversion of CO2 to High Value Hydrocarbon Products. Converting carbon dioxide (CO2) into hydrocarbon products is ideal for combating anthropogenic emissions whilst reducing our reliance on fossil fuels. Despite the significant advantages, CO2 valorisation is hindered by barriers such as high energy requirements and low-value products (methane and carbon monoxide). This project will establish a sustainable approach to CO2 valorisation using a unique tandem solar-driven hie ....Tandem Photocatalytic Conversion of CO2 to High Value Hydrocarbon Products. Converting carbon dioxide (CO2) into hydrocarbon products is ideal for combating anthropogenic emissions whilst reducing our reliance on fossil fuels. Despite the significant advantages, CO2 valorisation is hindered by barriers such as high energy requirements and low-value products (methane and carbon monoxide). This project will establish a sustainable approach to CO2 valorisation using a unique tandem solar-driven hierarchical catalyst array to offset energy requirements and directly yield high-value hydrocarbon products, such as ethane (C2H6) and ethanol (CH3CH2OH), from captured CO2.Read moreRead less
