Open Hydroponics: Risks and Opportunities

The aim of this assessment was to examine the irrigation supply related issues that relate to existing and more importantly potential enterprises undertaking Open Hydroponic (OH) irrigation within the major irrigation districts of Victoria and New South Wales. While this assessment looked at the irrigation of Citrus in particular, it did not exclude the use of OH on other crops and sought to address the supply issues for all (more)...

Open Hydroponics: Risks and Opportunities

The following report is a brief study and interpretation of the publicly known principles and theories of Open Hydroponics (OH). Scientific validation of the principles of OH, productivity gains from OH and in-field assessment of the practicality of OH was not a part of this study. Published information on OH was reviewed, however very little published information was (more)...

Open Hydroponics: Risks and Opportunities

The purpose of this component of the research was to develop a method to identify likely ecological risks associated with Open Hydroponics (OH) in the Mallee region, using an ecological risk assessment approach. Ecological Risk Assessment (ERA) is the process of defining and assessing the risks to ecological resources of anthropogenic hazards and determining the acceptability of those risks. The hazard(s) can be any chemical, physical or (more)...

Open Hydroponics: Risks and Opportunities

The aim of the workshop was to:

• Update and discuss the results of the project with team members, affiliated contributors and nominated stakeholders
• Develop recommendations for stage two of the project

Open Hydroponics: Risks and Opportunities

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.

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

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)...

Adopting Open Hydroponics

Adopting an Open Hydroponics management program requires a reliable water supply, a significant investment in capital infrastructure, an increase in operating costs and a change in management skills. All of these factors need to be considered before a decision is made to adopt Open Hydroponics. This fact sheet covers the following; Understanding Open Hydroponics Water Requirements Productivity claims Management skills (more)...

Introduction to Open Hydroponics

Open Hydroponics is an irrigation and nutrition management program aimed at increasing yield and fruit quality of horticulture crops. The fundamental principle of Open Hydroponics is that nutrients are applied continuously by drip irrigation that is operated at very high frequency. Design, installation, operation, monitoring and control are all critical components of Open Hydroponics. Professor Rafael Martinez (University Miguel Hernández, Spain) was the first to introduce the concepts of Open (more)...
