This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less

Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient lea ....Enhancing nutrient retention in soils through management of microbial biomass. Soil microbial-processes are generally studied in relation to mineralisation of nutrients but rarely for their potential to retain nutrients and reduce nutrient leaching. We hypothesise that management of microbial immobilisation will enhance nutrient retention in nutrient enriched soils during seasonal rains. This hypothesis will be tested under strongly seasonal environments of southwest Australia where nutrient leaching from soils degrades quality of surface and groundwater. We will first investigate pathways and conditions leading to microbial immobilisation. We will then explore the regulation of substrate and nutrient conditions to promote such retention, and subsequently develop management interventions based on microbially-mediated nutrient retention.Read moreRead less
More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
Maintenance of Australia's soil resource - water, microbial diversity and function. Water availability is the major limitation to biological activity in semi-arid regions of Australia. We aim to quantify the dynamic relationships between organic matter cycling, microbial diversity and function in relation to seasonality, drought and land management. This will lead to a comprehensive understanding of how water mediates the diversity of soil organisms and their associated functions.

Water availability is the major limitation to biological activity in semi-arid regions of Australia. We aim to quantify the dynamic relationships between organic matter cycling, microbial diversity and function in relation to seasonality, drought and land management. This will lead to a comprehensive understanding of how water mediates the diversity of soil organisms and their associated functions. This is of specific relevance to maintaining biodiversity within the unique soil ecosystems that have developed under Australian climatic conditions.Read moreRead less
Integrating microbiology and climatic drivers to determine triggers for nitrous oxide emissions from arable soils in semi-arid Western Australia. Increasing nitrous oxide emissions from soil to the atmosphere are a concern as they contribute to global warming and the destruction of the ozone layer. While 70-81% of this increase has been attributed globally to agricultural soils, the factors controlling emissions from arable soils in southern Australia are not well understood. We aim to charact ....Integrating microbiology and climatic drivers to determine triggers for nitrous oxide emissions from arable soils in semi-arid Western Australia. Increasing nitrous oxide emissions from soil to the atmosphere are a concern as they contribute to global warming and the destruction of the ozone layer. While 70-81% of this increase has been attributed globally to agricultural soils, the factors controlling emissions from arable soils in southern Australia are not well understood. We aim to characterise and model the relationship between the soil microbial community responsible for nitrous oxide emissions and soil water availability. Understanding the processes responsible for nitrous oxide emissions will enable us to change the way we manage our semi-arid soils so as to minimise nitrous oxide emissions.Read moreRead less
The impact of water logging on mitochondrial metabolism in leaves and roots of Grey poplar. Water logging and flooding are seasonal occurrences in a variety of environments. These events cause various damage to environments, including damage to plants. The damage to plants has traditionally been associated with annuals, such as various crop species. However larger plants, i.e. trees, are also very susceptible to water-logging and flooding.

Water logging and flooding are seasonal occurrences in a variety of environments. These events cause various damage to environments, including damage to plants. The damage to plants has traditionally been associated with annuals, such as various crop species. However larger plants, i.e. trees, are also very susceptible to water-logging and flooding. As it can take from several years to decades for tress to be established it is important to understand how trees can withstand water-logging and flooding. As tree plantation are uses for commercial and environmental purposes this knowledge will be useful to a broad spectrum of users in the community.Read moreRead less
Cellular automata model of forest stands to predict size-class distribution and survival. Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning.

Existing forest growth models predict well stand level processes such as growth. However, they provide little information on forest structure and how this affects commercial forest products, risks of growing plantations and stand dynamics that determine carbon sequestration and water-use and result in age-related decline in productivity and self-thinning. By using newly developed technology to quantify inter-tree competition, tree level resource supply, between tree genetic differences and the importance of chance events this project will draw on complexity theory to develop an innovative model that partitions stand level production to forecast the growth and size of individual trees.Read moreRead less

This project will elucidate quantitative relationships between growth and the levels of root-zone salts and water. The results will enable development of best practices for use of salt-tolerant turfgrass species, to (i) improve aesthetics of many rural and coastal towns faced with salinity, and (ii) enable use of saline groundwater, and thus conserve precious potable water, reducing costs of water for irrigation. The project is also of relevance to saline agricultural areas, as the species investigated could also have applications in saltland pastures. The outcomes will contribute to National priorities dealing with salinity management and protection of water resources. Read moreRead less
