Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. 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 in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. 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
Understanding salt and water dynamics to enhance the quality of turfgrasses irrigated with saline water in a Mediterranean environment: an evaluation of four species. 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 ....Understanding salt and water dynamics to enhance the quality of turfgrasses irrigated with saline water in a Mediterranean environment: an evaluation of four species. 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
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. As it can take from several years to decades for tress t ....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. 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
