Land use effects on soil nutrient enrichment: risks for weed invasion

Appendix

This project examined various soil and vegetation properties of remnant eucalypt grassy woodlands under different livestock grazing regimes within agricultural landscapes on the southern tablelands and south west slopes of N.S.W. All woodlands contained…

Inland river floodplains: the role of sediment and nutrient exchanges

Rivers around the world are under increasing pressure from a variety of human activities. Effective management of riverine landscapes requires an ecosystem approach and one that recognises the complex interactions between their physical, chemical and biological components. Perceptions of pattern and process are central to our understanding of riverine landscapes.

Fires impact water quality long after quenched

Leading research into the impact of the 2003 Alpine bushfires on water quality suggests the trouble is far from over when the fires are finally out. In the past, the impact of fires on water catchments could only be estimated, as the unpredictable nature of fires left very little possibility for collecting strong data.

River contaminants: salt, nutrient, sediment and their interactions

Using Wetting Front Detectors in Furrow Irrigation

The Wetting Front Detector (WFD) is a new tool to help measure how deeply water has penetrated into the soil after an irrigation event. The WFD also captures and stores a soil water sample, which can be analysed for its salt or nutrient content. The first commercial version of the Wetting Front Detector (WFD), called the FullStop, was released in 2004. The FullStop WFD is comprised of a (more)...

Wastewater recycling in nurseries

National Program for Sustainable Irrigation Fact sheet 2005/3

Reducing water run-off, minimising nutrient leaching and optimising irrigation efficiency are major challenges for the nursery industry. A comprehensive review of Australian and international research programs covering all aspects of waste water management in nurseries has been carried out by Horticulture Australia Limited (HAL) - a funding partner for the National Program for Sustainable Irrigation. The review identified useful resources for the industry and best practice in (more)...

Open Hydroponics - Risks and Opportunities - Stage 1 Project Findings Overview

National Program for Sustainable Irrigation Fact Sheet

Open Hydroponics (OH) is an innovative horticultural management program with over 2700ha currently being adopted in Australia and presents an opportunity for more sustainable production (economic and environmental). Conventional drip irrigation growers are also adopting selected Open Hydroponic principles, which use similar practices and carry the same possible benefits and environmental risks. OH aims to increase productivity by (more)...
