The project was developed to test the hypothesis: a depressed leaching efficiency (LE) in the Lower Murray irrigation districts raises the root zone salinity and, improved water use efficiency (WUE) has an upper limit determined by that field's LE and its variance'. The specific objectives were to: Determine/update the salinity relationships for irrigated horticulture along the Lower

This guide is designed to assist growers in managing irrigation with recycled water. Like any water source, you will need to ensure that the water quality and its management meet the requirements of your specific quality assurance (QA) scheme. You may also need to meet additional government regulatory requirements for the use of recycled water for horticultural crops. From a crop management perspective, you may need to make some minor changes, since the quality of

Irrigated farm businesses currently face a number of problems--reduced water allocations and river flows, increased climate variability, and economic pressures. In order to remain profitable and increase the productivity of water supplies, urgent action is required.

These appendices form part of and should be read in conjunction with the Northern Australia Irrigation Futures (NAIF) National Program for Sustainable Irrigation CDS23 final report, which contains a synthesised view of all the NAIF work carried out.

The work of Dr Bruce Cockroft has established the importance of managing soil structure in irrigated horticulture in Australia. In particular, he has researched and promoted management strategies designed to maximize the rooting volume of irrigated crops with consequent substantial improvements in yield. These strategies have focused on the creation and maintenance of good soil structure and structural stability and of low resistance to penetration, particularly in soils that are of poor

Milestone report

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,

This Irrigation Insights information package brings together information on current equipment and techniques for measuring and monitoring soil water status, extending to their use as controllers in automatic irrigation systems. We have limited the equipment described here to those products with agents and backup within Australia. The hub of the publication is a collection of tables summarising the main product features. This enables you to compare product features. As well as technical data, there is also commercial information on suppliers, contact details, availability and price (accurate at August, 2000). Case studies from personal experience and from the literature provide further insight into the advantages and limitations of each device in relation to its potential applications.
