Quality

Flow requirements and resource delivery to the Lower Murray Lakes and Northern Coorong

As discussed in the previous milestone reports, the drawdown of water levels in the Lower Lakes to unprecedented levels has provided an additional focus for the project. This has been done to provide relevant information to the managers and assist with both the short-term and long-term management of the region. It has included investigating the changes water quality during drawdown and likely changes in water quality upon reflooding the lakes.

Socio-economic research and development for irrigation communities

The case for maintenance of a healthy environment that supports sustainable economic activity and offers economic, social and environmental benefits, has been well argued. All stakeholders, whether farmers, governments, non-government organisations or industry in all its forms, have a crucial role in this process, as decisions and actions of stakeholders at all levels greatly affect outcomes from use of water and other natural resources. In many catchments, new approaches to the use (more)...

Polyacrylamides in Irrigated Agriculture

Polyacrylamide (PAM) has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. PAM’s soil stabilizing and flocculating properties have also substantially improved runoff water quality by reducing sediments, N, ortho and total P, COD, pesticides, weed seeds, and microorganisms in runoff. The first series of practical field tests of (more)...

Assessment of ecological risk associated with irrigation in the Fitzroy basin

This project in the Fitzroy catchment in Queensland was one of three case studies used to illustrate how ERA may be employed in the management of irrigation areas in Australia. In the problem formulation stage of the ERA process community stakeholders identified issues and helped to prioritise research needs for the second phase. These were that the research should focus on the irrigation area scale and the impact of the decline of water quality on (more)...

Introduction to Open Hydroponics

Open Hydroponics is an irrigation and nutrition management program aimed at increasing yield and fruit quality of horticulture crops. The fundamental principle of Open Hydroponics is that nutrients are applied continuously by drip irrigation that is operated at very high frequency. Design, installation, operation, monitoring and control are all critical components of Open Hydroponics. Professor Rafael Martinez (University Miguel Hernández, Spain) was the first to introduce the concepts of Open (more)...
