An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses ....An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications. We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses of N, P from fertilisers will be investigated. The major outcome of this research will be effective and inexpensive procedures for reducing eutrophication due to N, P from waste water and fertilisers.Read moreRead less

Tracing nitrogen through wet tropical aquifers using stable isotopic signatures, molecular markers and gas emissions. The project aims at enabling land managers to reduce the loss of nitrogen into creeks, rivers and estuaries of the Great Barrier Reef catchments. This will improve the economic and environmental viability of primary production while restoring the quality of aquatic and marine ecosystems. The results will identify parts of the landscape where land management needs to change and ov ....Tracing nitrogen through wet tropical aquifers using stable isotopic signatures, molecular markers and gas emissions. The project aims at enabling land managers to reduce the loss of nitrogen into creeks, rivers and estuaries of the Great Barrier Reef catchments. This will improve the economic and environmental viability of primary production while restoring the quality of aquatic and marine ecosystems. The results will identify parts of the landscape where land management needs to change and over what time scale improvements would be apparent. These outputs address the water quality priorites and targets of the 'Reef Water Quality Protection Plan' of the State and National governments and the 'Far North Queensland Natural Resource Management Plan'.Read moreRead less

Improving the efficiency of use of agricultural chemicals, through utilization of novel liquid crystalline carriers particles, will deliver significant environmental and economic benefits. Reduced overall usage and input of chemicals into the environment, together with lower water consumption in the treatment of crops will contribute to an Environmentally Sustainable Australia, with benefits in reduced salinity. More economical farming will also lead to flow on benefits to other businesses in rural communities. The project will also enhance Australia's reputation in the uptake of nanotechnologies, and in training of young scientists in the nanotechnology field.Read moreRead less
Mechanistic and probabilistic approaches to assessing the impact of pesticide mixtures in Australian waterways. This project will provide vital information on the impacts of pesticide mixtures in Australian waterways and will also provide information with respect to safe levels of pesticides for water quality management.

This project will provide vital information on the impacts of pesticide mixtures in Australian waterways and will also provide information with respect to safe levels of pesticides for water quality management. This information will be used to develop scientifically sound management policies and provide advice to regulatory authorities such as the NSW Department of Environment and Conservation and the Federal Department of Environment and Heritage. Specifically the results will contribute to ensuring the use of pesticides in market gardens close to Sydney does not threaten the health of local rivers. Read moreRead less

Summary
Upgrading of Wind Tunnel Research Facility with Oxford Lasers VisiSizer. Bringing together expertise within five collaborating research Centres in two Universities, an Oxford Lasers VisiSizer will be used to study the atomisation of pesticide sprays and droplet behaviour in moving flow fields. This equipment, in conjunction with the construction of a new working section in a pesticide wind tunnel research facility, will enable the simultaneous measurement of particle size and droplet velocity.

Bringing together expertise within five collaborating research Centres in two Universities, an Oxford Lasers VisiSizer will be used to study the atomisation of pesticide sprays and droplet behaviour in moving flow fields. This equipment, in conjunction with the construction of a new working section in a pesticide wind tunnel research facility, will enable the simultaneous measurement of particle size and droplet velocity. The VisiSizer will construct images of the atomisation process and enable the interaction of spray droplets and plant canopies to be studied. Data will support modelling of pesticide transport processes and accelerate leading Australian expertise in pesticide science.Read moreRead less
Minimising environmental and public health risk of pesticide application through understanding the droplet-canopy interface. Pesticides are essential tools for agricultural industries in most Australian cropping systems. Accurate placement of pesticide droplets onto plant surfaces is the key step in guaranteeing high quality food production, while loss of droplets to air and soil are inefficiencies leading to environmental and public health risks.

Pesticides are essential tools for agricultural industries in most Australian cropping systems. Accurate placement of pesticide droplets onto plant surfaces is the key step in guaranteeing high quality food production, while loss of droplets to air and soil are inefficiencies leading to environmental and public health risks. Innovations in plant architecture informatics will be used to develop an improved understanding of droplet/plant canopy interactions that will be validated through wind tunnel experimentation. This research will result in a risk assessment tool that can be applied generally to controlled spray applications of pesticides.Read moreRead less
Conversion of Lignite to Biochars to Enhance Soil Fertility. Lignite, or brown coal, is used in power generation, but it is uneconomic to transport and acts as a significant source of greenhouse gases. The conversion of lignite to liquid fuel and char provides an economic source of fuel and the generation of a char which also lowers the carbon footprint associated with lignite processing. Lignite-derived char has potential to act as an agent for both promoting plant growth and improving soil hea ....Conversion of Lignite to Biochars to Enhance Soil Fertility.

Lignite-derived char has potential to act as an agent for both promoting plant growth and improving soil health. This project will do much to promote the use of chars, from a lignite source, which will increase the economic viability of mining brown coal. Read moreRead less

Nutrient generation from rural land and delivery to streams in the Sydney Drinking Water Catchments. The Sydney Catchment Authority must manage pollution arising from land within its catchments. There have been few local studies of nutrient losses from rural land, the major land use, and the understanding of some important processes involved in nutrient generation and delivery is weak. Therefore model predictions are uncertain.

The Sydney Catchment Authority must manage pollution arising from land within its catchments. There have been few local studies of nutrient losses from rural land, the major land use, and the understanding of some important processes involved in nutrient generation and delivery is weak. Therefore model predictions are uncertain. This project will quantify nutrient losses from key land uses, evaluate alternative loss pathways, and provide insight into the effects of scale, providing a foundation for improved modelling of nutrient sources and transport. The outcome will be the capacity to prioritise land uses and parts catchments for remedial action, whilst providing a modelling approach relevant to the SCA and other catchment managers.Read moreRead less
