Optimising delivery and benefits of aerated irrigation water

We have shown in a number of annual crops that by simply creating air bubbles in drip irrigation systems we can significantly increase crop yield and quality, overcoming root oxygen starvation caused by irrigation. We will trial this practice [we call it oxygation] on perennial species in growers’ fields firstly in Queensland, and then halfway through the project in NSW and SA, to improve yield and yield per unit of water use.

Partitioning almond evapotranspiration

Samantha Conner will be taking measurements of evporation rates from soil in an almond orchard. Samantha will be working as part of the larger research project “Developing a reliable model of drainage production from irrigated horticulture at the farm and district level". Samantha will be undertaking her project as part of her final year of undergraduate studies at Flinders University.

Quantifying surface water - groundwater exchange using thermal & chemical measurements

This project will develop field equipment and a proven scientific methodology that will quantify surface water - groundwater transfer to aquifers beneath river beds and therefore contribute to the mapping of the many and complex connections and interactions between groundwater and the surface water - dams, lakes, rivers, wetlands.

Remote sensing data and crop water measurements

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.

Review of Precision Irrigation Technologies and their Application

Despite the widespread promotion and adoption of precision agriculture in dry land cropping systems, the concept of irrigation as a component of precision agricultural systems has not been widely canvassed. Irrigation application is commonly viewed as a less than precise activity and the potential for precision irrigation is yet to be adequately evaluated. This project will review irrigation research, existing technologies and the use of precision irrigation. It will include an assessment of the role of (more)…

Root Zone Water, Salinity and Nutrient Management Under Precision Irrigation

The SRD8 project has an ongoing commitment to the development of salinity risk management strategies and tools designed to limit the damaging effects of salinity in the root zone, a fact that is most clearly represented by the establishment of 20 trial sites distributed through a range of growing conditions in SA, NSW and VIC.

Soil Management for Australian Irrigated Agriculture

Australian soil structure deteriorates rapidly under irrigation with current management practices, resulting in inefficient water use and low yields. These soils lack the mineral montmorillonite present in those overseas soils which maintain porosity and stability under irrigation. This (more)…

Soil Water Monitoring Irrigation Insight, Second Edition

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.
The main part of the package focuses on equipment with agents and backup within Australia. The hub of the publication is a collection of tables summarising the main product features. This enables rapid comparison of product features.
As well as technical (more)…

The Economic Benefits of Irrigation to National and Regional Economies

This study uses a modified version of the Centre for International Economics’ (CIE) economywide general equilibrium model of the Australian economy. This modelling framework allows the net economic value of the irrigation sector to be quantified both in terms of its direct contribution to gross domestic product (GDP) and employment, and the indirect contributions, which capture the economic linkages between the irrigation sector and other sectors (more)…
