Role of stubble management in improving soil fertility. In highly-weathered nutrient-poor soils of the south-western Australia, the amount of nutrients in stubble is critical in nutrient cycling as well as in determining optimal amounts of fertilisers to be applied. Stubble management is therefore an integral part of crop fertilisation and nutrient management. We will characterise nutrient cycling in the stubble-soil-crop continuum in a range of cropping situations. Computer modelling will be us ....Role of stubble management in improving soil fertility. In highly-weathered nutrient-poor soils of the south-western Australia, the amount of nutrients in stubble is critical in nutrient cycling as well as in determining optimal amounts of fertilisers to be applied. Stubble management is therefore an integral part of crop fertilisation and nutrient management. We will characterise nutrient cycling in the stubble-soil-crop continuum in a range of cropping situations. Computer modelling will be used to extend applicability of results over space and time. This project will provide the knowledge required for improving fertiliser recommendations to take into account changes in the cropping systems that have occurred in the last 10-20 years.Read moreRead less
Improved Indian Mustard for sustainable biodiesel production. There is an urgent need to reduce Australia's dependency on fossil fuels and to improve the sustainability of the Australian farming sector. The on-farm production of biodiesel will reduce farm input costs, reduce farmer dependency on fluctuations in fossil fuel costs and reduce greenhouse gas emissions. Indian mustard is drought tolerant and produces inedible oil suitable for biodiesel production. The genetic improvement of Indian mu ....Improved Indian Mustard for sustainable biodiesel production. There is an urgent need to reduce Australia's dependency on fossil fuels and to improve the sustainability of the Australian farming sector. The on-farm production of biodiesel will reduce farm input costs, reduce farmer dependency on fluctuations in fossil fuel costs and reduce greenhouse gas emissions. Indian mustard is drought tolerant and produces inedible oil suitable for biodiesel production. The genetic improvement of Indian mustard will provide farmers with a viable crop for biodiesel production and its bio-fumigation properties make it an effective addition to the crop rotation. Useful by-products include a natural insecticide and, once the glucosinolates are removed, meal suitable for animal feed. Read moreRead less
Managing subsoil constraints for increased productivity and water use efficiency. Subsoil constraints limit crop production in up to 60% of agricultural land. This project examines the impacts of organic matter incoporation, deep placement of nutrients, use of primer crops, calcium addition and their combination on amelioration of subsoil constraints and thereby on the improvement of root growth, water use and crop yield in high-rainfall region. The best-bet management strategy will be developed ....Managing subsoil constraints for increased productivity and water use efficiency.

Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a nov ....Role of alanine aminotransferase in improved nitrogen use efficiency (NUE) in cereals. The use of nitrogen-based fertilisers by crop plants is poor where efficiencies (nitrogen taken up to that applied) is often less than 40%. Nitrogen not used is often lost to the environment through leaching and or volatilisation. Improving nitrogen use efficiency (NUE) in agriculture will decrease overall nitrogen fertiliser use and minimise its environmental footprint. This project will characterise a novel NUE technology that when transferred to plants significantly improves NUE. We will define the phenotype at the molecular, biochemical and physiological levels to maximise its adoption to other agricultural crops such as wheat, barley and maize.Read moreRead less
