Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driv ....Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driven seasonal forecast system using high density climate data from the 17,000 Grain Growers Association members and climate drivers such as sea surface temperature from the Bureau of Meteorology. After validation against observed data, the forecasts will be delivered via a web-based portal to users.Read moreRead less

Plant-microbial interactions can increase vegetative growth and crop yield. These PGPR effects result from improved N and P nutrition, stimulation of root growth, disease control, altered environmental conditions and, most importantly, positive interactions between all these. This project aims to develop plant growth promoting bacteria and fungi as commercial products. By matching microbes to plants and soil environments, a set of peat-based inoculants will be optimised for application as biofertilisers to field crops and turfgrass.
Potential applications are both rural and urban.
The outcomes will be proven commercial products able to promote plant growth and rapid recovery from adverse conditions.Read moreRead less

Selling grain produced in certified biological farming system will attract market premium, therefore enhancing the position of Australian farmers. This project will produce fertiliser recommendation systems incorporating organic fertilisers, thus decreasing costs of production and maintaining clean and healthy environment.Read moreRead less
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

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
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 national benefit of the remote sensing of water and nutrient levels in crops comes from improved agricultural practice; leading to cost savings, reduced water usage and reduced pollution. This benefit will arise since irrigation and fertiliser application can be exactly tailored to the measured needs of broad-acre crops. In Australia, water is a scarce resource. Reducing consumption by irrigators will have significant downstream benefits. By remote measurement of nutrient variation within paddocks, fertiliser applications can be optimised. Minimum excess fertiliser will then be present and this will minimise runoff and potential downstream water pollution.Read moreRead less
