With recent advances in technology irrigators can now more precisely control delivery of mineral nutrients and water to the roots of perennial tree crops. These technologies, collectively referred to as fertigation, provide the opportunity to adopt and implement highly technical management programs, such as open hydroponics, that use drip irrigation to deliver a balanced mixture of nutrients and water. This research bulletin provides an overview of a project, funded by the National (more)...
This project examined relationships between hydrological parameters relating to flooding and the location and abundance of exotic plant species in River Murray floodplain systems.
Weeds cost the Australian economy millions of dollars each year in lost production, eradication, containment and management, however there has been very little effort placed on assessing or valuing the ecological impact of these weeds.
Exploring the technical, management and policy challenges - summary report
Groundwater and surface water resources are often closely linked. This has particular implications for Australia and how we manage our water. As a result of this connectivity it is possible to allocate the same resource twice, to surface water users and to groundwater users. This double allocation of the same water has reduced the flow in our rivers and streams.
There has never been a nationwide review of surface water and groundwater interaction in Australia and consequently the extent of (more)...
