Economic evaluation of outcomes from investment in the National Program for Sustainable Irrigation

The National Program for Sustainable Irrigation Phase 2 (NPSI II) is a partnership between a number of research agencies, irrigation industries, water management authorities and state and federal governments. Investment through NPSI II will conclude on 25th June 2012. BDA Group was commissioned to undertake an economic evaluation of NPSI (more)...

New technology to reduce water evaporation from large storages

This report describes laboratory work carried out to evaluate and further optimise the chemical and physical formulation of the proposed new ultra-thin film product. Three chemical systems were evaluated—EX1, EX2 and EX3.

Irrigation Essentials - updated 2012

This report captures the key principles of sustainable irrigation at the farm scale. And is an update including recent research. The NPSI Knowledge Harvest brings together information from across the National Program for Sustainable Irrigation (NPSI) projects, highlighting key findings and promoting wider understanding. Key Harvest themes: Irrigation Overview – facts, figures and key concepts (more)...

Guidelines for Fertigating Citrus Orchards

Managing fertigation systems to achieve good productivity and avoiding fertiliser wastage and loss.

Irrigation Channels

Evaporation water losses from irrigation channels are an important component of total irrigation system losses and could be as much as 12% in the Goulburn Murray channel network. The effectiveness of monolayers has been widely studied in still water storages. This research project investigated the potential of using chemical monolayers on irrigation channels in order to suppress evaporation.

Sensor and control system development for autonomous site-specific irrigation

The NPSI/IAL Travel Fellowship 2010 aimed to investigate developments toward autonomous site-specific irrigation control systems. Site-specific irrigation systems offer improvements in water use efficiency and crop performance by differentially applying irrigation to the field when and where it is required.

Subsoil structure in irrigated Australian vineyards

Good soil structure is essential for healthy, resilient plants because it allows them to develop extensive, active root systems. This promotes efficient use of water and nutrients, encourages biological activity and buffers plants against drought and other hardship. It is a neglected, but vital component of soil fertility.

Travel Fellowship Report

The topic of this travel fellowship was the water-energy-emissions nexus in irrigated agriculture. This fellowship allowed Tamara to meet with world class researchers working on various aspects of this topic, extending her network of industry contacts. A key benefit was the exposure to the latest research and ideas, which will provide an opportunity for these to potentially be adapted to the Australian situation. Similar research carried out as part of her PhD studies and (more)...
