Environment, Management and Compositional Quality of Fruit and Wine of the Grapevine, 'Chardonnay". This project seeks to maintain Australia`s competitive edge in the ultra premium and icon global wine market by seeking to identify new objective descriptors for Chardonnay. These can then be applied across the full spectrum of sites, climates and management for this variety.

This project seeks to maintain Australia`s competitive edge in the ultra premium and icon global wine market by seeking to identify new objective descriptors for Chardonnay. These can then be applied across the full spectrum of sites, climates and management for this variety. It comprises three sub-programs that are integrated with vineyard and winery management: 1, natural product chemistry of fruit, 2, fine-scale, vine biology in relation to site, season and management, and 3, complex systems analyses applying modern database, multivariate and data-mining technologies to assess and communicate visually, the key drivers of compositional quality.Read moreRead less
Compost extract: a new paradigm for disease management in sustainable horticulture. There is significant legislative and consumer pressure worldwide to reduce the amount of pesticide applied to food crops. Compost extract is a watery extract of mature compost that when applied to a crop canopy allows simultaneous suppression of a broad range of plant diseases while maintaining biodiversity in an agricultural ecosystem. This technology represents a paradigm shift from the monoculture approach o ....Compost extract: a new paradigm for disease management in sustainable horticulture. There is significant legislative and consumer pressure worldwide to reduce the amount of pesticide applied to food crops. Compost extract is a watery extract of mature compost that when applied to a crop canopy allows simultaneous suppression of a broad range of plant diseases while maintaining biodiversity in an agricultural ecosystem. This technology represents a paradigm shift from the monoculture approach of single-target fungicides or biological control agents. Scientific evaluation has been hampered by a lack of standard production techniques. Our aim is to identify and characterise compost extract technology that produces known and consistently high levels of effectiveness and safety.Read moreRead less

Summary
Isotope Ratio Mass Spectrometry Facility for Nitrogen and Water Analysis in Plants. Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth anal ....Isotope Ratio Mass Spectrometry Facility for Nitrogen and Water Analysis in Plants. Continual improvement to agricultural plant production is key to maintaining future sustainable growth in Australian agriculture. Our respective research teams are focussed on improving how plants utilise both nitrogen and water. Many questions remain with respect to where, how and when plants use and or access these important nutrients. The proposed facility will enable plant scientists to begin in-depth analysis of both nitrogen transport mechanisms and the ability to model root development and water allocation in crop species. This research will ultimately lead to improved knowledge on how plants respond to their environment and where modifications can be made to generate sustainable crops suited to Australian agriculture.Read moreRead less
Control of foliar diseases in horticulture using milk components: widening applicability through understanding mechanisms. Fungal diseases, such as powdery mildew and botrytis grey mould, have the potential to cause considerable losses in horticultural crops. Chemical fungicides, some of which are broad-spectrum biocides potentially harmful to human health, are applied routinely in disease management. Milk and whey, which can damage powdery mildew fungi, offer alternatives to conventional fungic ....Control of foliar diseases in horticulture using milk components: widening applicability through understanding mechanisms. Fungal diseases, such as powdery mildew and botrytis grey mould, have the potential to cause considerable losses in horticultural crops. Chemical fungicides, some of which are broad-spectrum biocides potentially harmful to human health, are applied routinely in disease management. Milk and whey, which can damage powdery mildew fungi, offer alternatives to conventional fungicides. Identification of the components of milk which damage fungi, and their mechanisms of activity, will facilitate the development of environmentally sustainable strategies for management of fungal diseases in Australian horticulture. This will have particular benefits for personnel who regularly apply fungicides in glasshouses.Read moreRead less
Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable du ....Influence of high temperature on phenology, metabolism and the fate of axillary buds and inflorescences in grapevine. Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less
Unravelling the links between plant transpiration, soil water and nitrate movement: impact of high atmospheric CO2 and irrigation strategy. Australia's serious environmental problems, soil salinity and acidity, may be greatly affected by rising atmospheric CO2 and irrigation strategies. This will occur if the movement of soil water and nitrate changes with transpiration. We will generate different transpiration rates by varying atmospheric CO2 above pastures and irrigation strategies in vineya ....Unravelling the links between plant transpiration, soil water and nitrate movement: impact of high atmospheric CO2 and irrigation strategy. Australia's serious environmental problems, soil salinity and acidity, may be greatly affected by rising atmospheric CO2 and irrigation strategies. This will occur if the movement of soil water and nitrate changes with transpiration. We will generate different transpiration rates by varying atmospheric CO2 above pastures and irrigation strategies in vineyards. The commercial partner's newly developed soil sensors allow, for the first time, simultaneous 3-D measurement of soil water and nitrate in real-time. The results will answer long-standing questions about impacts of transpiration rates on plant nitrogen uptake and generate valuable new knowledge for sustainable management of pastures and horticultural crops.
