Phytoremediation of arsenic contaminated sites using arsenic hyperaccumulating plants. The legacy of using arsenical compounds in pest control activities has resulted in many contaminated sites. Since the inorganic arsenic is carcinogenic, stringent laws have been enforced to control arsenic (As) in the environment. This project investigates the potential of using the recently discovered (Ma et al, 2001) arsenic hyperaccumulating (22,000 mgAs/kgDW) fern, Pteris vittata, in the removal of arsen ....Phytoremediation of arsenic contaminated sites using arsenic hyperaccumulating plants. The legacy of using arsenical compounds in pest control activities has resulted in many contaminated sites. Since the inorganic arsenic is carcinogenic, stringent laws have been enforced to control arsenic (As) in the environment. This project investigates the potential of using the recently discovered (Ma et al, 2001) arsenic hyperaccumulating (22,000 mgAs/kgDW) fern, Pteris vittata, in the removal of arsenic from dip sites and railway tracks in Qld, and orchards in northern NSW. The impacts of growing hyperaccumulating plants on grazing animals and the environment, and the disposal of arsenic from contaminated plants will also be studied.Read moreRead less

Control of plant pests relies on the heavy use of chemical insecticides that cause an extraordinary impact on the environment. Some insect pests have been controlled by the production of toxins (like BT) by the plant. We will combine newly discovered RNA interference and genomics methods to develop innovative solutions to nematode resistance and insect control. Our methods can be tailored to any pest with wide or narrow spectrum of action and does not require the production of toxins by the plant. The novelty of our approach will generate a large amount of intellectual property.Read moreRead less
Protection of Botanical Innovation: A legal analysis of the scope and operation of national and international plant breeder's rights. Plants play a crucial role in Australian society: they are a major source of nutrition, shelter, clothing, fuel, medicines and aesthetic pleasure.

Plants play a crucial role in Australian society: they are a major source of nutrition, shelter, clothing, fuel, medicines and aesthetic pleasure. They also make an important contribution to the Australian economy. The legislative regime established under the 1994 Plant Breeder's Rights Act was designed to promote research, investment and innovation in Australian plant breeding. A lack of familiarity and widespread misunderstanding mean that the system is under-utilised with adverse consequences for plant innovation and Australia's economy. This groundbreaking research will provide a comprehensive analysis of plant breeder's rights in Australia to maximise understanding and awareness amongst key stakeholders.Read moreRead less
Conservation tillage and its potential to affect catchment salt and water balances. Replacement of deep-rooted vegetation with shallow rooted crops has resulted in greater movement of water into groundwater systems, raising in groundwater level and mobilizing salt to the land's surface. The practice of conservation tillage, provides a range of advantages to landholders, but also has the potential to accentuate the risk of salinisation because it increases water infiltration into the soil surfac ....Conservation tillage and its potential to affect catchment salt and water balances. Replacement of deep-rooted vegetation with shallow rooted crops has resulted in greater movement of water into groundwater systems, raising in groundwater level and mobilizing salt to the land's surface. The practice of conservation tillage, provides a range of advantages to landholders, but also has the potential to accentuate the risk of salinisation because it increases water infiltration into the soil surface. This project aims to evaluate the impact of conservation tillage on soil salt profiles in the Condamine-Balonne and Border Rivers Catchments, and to model will the effect of changed landscape salt and water balances on river water quality.Read moreRead less

Domestic water consumption in Australia is approximately 30% higher than the OECD average. Approximately one third of domestic water consumption is applied to the garden, including turfgrass lawns. Turfgrasses are significant users of fertilisers, which can lead to problems with runoff and infiltration into the water table. We will use the unique diversity of Australian couch grasses to identify new turfs for domestic, sportsground and amenity lawns. This project will develop tools to select turfgrasses that maintain quality with reduced inputs of water and nutrients, leading to an overall reduction in resource use and downstream ecological effects. Benefits of this project extend to urban and rural communities Australia-wide.Read moreRead less
Controlled nutrient release for more efficient agricultural water use and reduced environmental insult. We will create a completely new type of coating for fertilizer granules. Clays that adsorb and slowly release phosphates and/or other nutrients will be exfoliated with cationic organic reagents to produce organoclay nanoparticles of greatly increased surface area. These will be polymerized with current and novel monomers to form nanocomposites, encasing the clay in a water-swellable matrix by ....Controlled nutrient release for more efficient agricultural water use and reduced environmental insult. We will create a completely new type of coating for fertilizer granules. Clays that adsorb and slowly release phosphates and/or other nutrients will be exfoliated with cationic organic reagents to produce organoclay nanoparticles of greatly increased surface area. These will be polymerized with current and novel monomers to form nanocomposites, encasing the clay in a water-swellable matrix by polymerization; this will enable both slow water perfusion and strong binding to the granules. The polymer and nanoclay properties will be tuneable to release targeted nutrients at an optimal rate for uptake by crops, reducing nutrient seepage into the environment.Read moreRead less
