Relocation of intensive crop production systems to northern Australia

To adapt to climate variability and a lack of irrigation water, businesses and growers in southern Australia, northern New South Wales and southern Queensland are, or are considering, migrating their businesses to northern Australia.

Using mulch to improve water use efficiency of in-ground native flowers

Monitoring of soil moisture fluctuations under mulched and un-mulched native flowers will provide valuable information in assessing the crop water use and potential water savings associated with adoption of this practise. This information would be valuable in encouraging growers to adopt best management practises for sustainable flower production.

Investigating use of irradiation for disinfestation on Custard Apples

The ability to access new international markets particularly New Zealand is the focus of this project for the custard apple industry. Custard apple require a fruit fly disinfestation treatment to access New Zealand markets. Irradiation has shown to be an effective treatment in other fruits and has the potential to be introduced in a relatively short time frame. The project will assess the effect of irradiation on the quality and storage life of custard apples simulating an international supply chain.

Improvement and Maintenance of Turf Demonstration Plots

DEEDI have built and maintained a living library of turf grass selections of 138 different turf cultivars. Material is also preserved in tubs in a protected growing environment. The maintenance and ongoing upgrading of these plots requires significant resources to maintain their integrity. As the plots have been in place since 2000, they are currently in need of significant repair. This project will assist in the improvement and maintenance of the turf library for the benefit of the turf industry producers and Australian turf research more generally.

Evaluating the effects of using a Silverwater technologies disinfestation system

This project aims to determine plant growth response to water treated with the Silverwater disinfestation system against plants that have been irrigated with non treated water. The trial will monitor and measure plant growth rates and health to identify any variations that can be attributed to the Silverwater Technologies disinfestation unit.
