Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non ....Unravelling the secrets of the rhizosphere of crops. Phosphate is one of the most important limiting nutrients for crop growth and production. Plant acquisition of soil phosphate largely depends on root proliferation to accelerate soil exploration, and on phosphate bioavailability mediated by root exudates and rhizosphere microorganisms. Central to this is the need for a better understanding of the complex biogeochemical interfaces in the rhizosphere. This project explores recently developed non-destructive imaging, isotope, and metabolism techniques to generate a systematic research tool in tracking rhizosphere interactions and imaging phosphate dynamics from macroscale to nanoscale levels. This study will provide new opportunities to improve crop nutrient use efficiency and crop production.Read moreRead less
Rhizosphere priming regulates soil carbon cycle under high carbon dioxide. Australian farmers will be producing crops under elevated CO2 in the future. However, it is unknown how the increased CO2 level will affect agricultural production and soil health. This project aims to understand the effect of high atmospheric CO2 on carbon and nitrogen cycles in major cropping soils. It will examine how combinations of crop and soil types lead to differences in loss of soil organic carbon.

However, it is unknown how the increased CO2 level will affect agricultural production and soil health. This project aims to understand the effect of high atmospheric CO2 on carbon and nitrogen cycles in major cropping soils. It will examine how combinations of crop and soil types lead to differences in loss of soil organic carbon. Soil microorganisms that link to carbon and nitrogen cycling in soils will be examined in the long-term field trials. The project intends to provide fundamental information that is essential to evaluate the future impact of climate change on the fertility and productivity of our poor, already infertile soils in semi-arid regions.Read moreRead less
A soil ecological approach to increasing Australian crop productivity. The objective of this project is to use emerging genomics technologies to identify and characterize soil bacteria that allow the replacement of current agricultural fertilisers, which have significant environmental and economic disadvantages, with sustainable biological fertilisers.

The objective of this project is to use emerging genomics technologies to identify and characterize soil bacteria that allow the replacement of current agricultural fertilisers, which have significant environmental and economic disadvantages, with sustainable biological fertilisers. Soil bacteria can greatly enhance phosphate solubilization and hence availability for plant growth. Beneficial microbes will be identified from our existing soil collection and their performance and persistence optimised. Concurrently, our industry partners will develop suitable microbial formulations for application. The outcomes of the project will be the use of biological fertilisers to enhance crop productivity in an environmentally sustainable manner.Read moreRead less
Multitrophic interactions drive diversity-ecosystem function relationships. Soil communities, among the most abundant and diverse in nature are responsible for many critical ecosystem functions, including nutrient cycling and climate regulation. This project will determine whether consideration and quantification of interactions between different biotic communities – specifically among plants, soil microbes and animals, within and across trophic levels - can address underlying shortcomings in pr ....Multitrophic interactions drive diversity-ecosystem function relationships. Soil communities, among the most abundant and diverse in nature are responsible for many critical ecosystem functions, including nutrient cycling and climate regulation. This project will determine whether consideration and quantification of interactions between different biotic communities – specifically among plants, soil microbes and animals, within and across trophic levels - can address underlying shortcomings in predictions from classical biodiversity-ecosystem function theory. By advancing understanding of biological complexity and its impacts on ecosystem functions, the project will provide a unifying framework for understanding variation in ecosystem functions across scales, ecosystem types and multiple environmental disturbances.Read moreRead less
The rare biosphere; discovering how soil bacteria live on air. In Antarctic deserts where photosynthetic potential is low, we discovered that soil microbiomes sustain their energy and carbon budgets through a novel process reliant on trace gases we coined 'atmospheric chemosynthesis'. But how do soil bacteria literally live on air? This project aims to reveal functional chemoautotrophic pathways in cultured soil bacteria that use trace gases as a source of energy and carbon acquisition. We will ....The rare biosphere; discovering how soil bacteria live on air. In Antarctic deserts where photosynthetic potential is low, we discovered that soil microbiomes sustain their energy and carbon budgets through a novel process reliant on trace gases we coined 'atmospheric chemosynthesis'. But how do soil bacteria literally live on air? This project aims to reveal functional chemoautotrophic pathways in cultured soil bacteria that use trace gases as a source of energy and carbon acquisition. We will perform biogeochamistry, transcriptomics and proteomics on the first model bacterial strains genetically capable of this overlooked process. Outcomes will advance knowledge on microbial metabolism, extending the repertoire of hydrogen-oxidising bacteria to soil ecosystem services, primarily primary production.Read moreRead less
The critical role of rhizosheath biophysics in plant water availability. This project aims to determine how plants can increase their water availability by altering the small volume of soil, rhizosheath that adheres to roots.

This project expects to integrate root exudates metabolomics, biophysics and microbial ecology to determine for the first time which of a suite of interconnected factors increase water availability in the root zone.
Expected outcomes include better understanding of the direct and indirect roles of soil pore geometry, root exudates and microbial communities play in shaping plant’s ability to take up water from soil. This knowledge may ultimately pave the way for engineering the rhizosheath of crops to cope with increased drought conditions.
