under supplementary irrigation drawn from saline groundwater
This publication explores ongoing perennial horticultural production using supplementary irrigation with saline groundwater. The role of rainfall, spatial distribution of salinity and salt-exclusion characteristics of rootstocks are among the considerations.
This publication outlines the framework for forward planning research, development and extension delivery for the irrigation industry and to assist the industry to contribute to several Australian Government Reviews considering research and development and extension/knowledge management in 2010.
The framework has been developed by the National Program for Sustainable Irrigation and Irrigation Australia Limited.
Production per unit of water, whether bales of cotton or tonnes of grain, may become a useful assessment of irrigation efficiency for individuals as well as whole industries.
In many regions of Australia there can be gaps between scientific community and general public understanding of water management issues. This bulletin outlines a framework for working together in the Ord River region using an initiative from the UNESCO International Hydrological Program called Health Environment Life Policy (HELP).
Oxygation of fig and pineapple crops was the interest of Central Queensland University student Michael Law, whose project built on investigations into the technique as a means of generating healthier interactions between water, soil and plant physiology.
Investigation of the relationships between remote sensing data recorded in satellite imagery and a comprehensive set of crop water measurements (taken in a vineyard and an almond orchard) was the project chosen by Flinders University of SA student Claire Williams.
The compilation of a clearer picture of the changing patterns of salt distribution in irrigated soil by Flinders University of SA student Megan Sebben under the supervision of the head of the South Australian Research and Development Institute’s Water Resources and Irrigated Crops Unit, Jim Cox.
Rising global demand for food offers a positive outlook for irrigators, with potential for higher commodity prices. However, producers face increasingly competitive and volatile markets, compounded by the global fnancial crisis. There are also looming shortages of water, as cities increase their demands, water is reallocated to improve the environment and flows are affected by climate change.
A researcher whose work has revolutionised management of water supplies through enabling early, rapid and accurate tests for toxicity has won the Land & Water Australia, Professor Peter Cullen Eureka Prize for Water Research and Innovation.
How much water do the wetlands of the Murray River need?
This project developed a model of the wetland plant community in 2,746 wetlands from the NSW and Victorian portions of the Murray River basin. The model used as data the average length of time out of each year each wetland was connected to the River Murray over the period 1990-2000. This value, called the connectivity, quantifies the wetting-drying cycle of a wetland. It describes the gradient between a (more)...
