Wastewater Recycling for Greenhouse & Hydroponic Vegetables: Watch and Learn

摘要

The Australian protected cropping industry is composed of approximately 1,665 vegetable growers producing in 1,341 ha of greenhouses. Currently, they contribute over $1.3billion farmgate value through the production of major vegetable crops.including cucumbers, capsicums, egg plants, tomatoes, lettuce, herbs, Asian greens and strawberries (of these numbers, 90% are growing in an artificial substrate or growing media to provide a nutrient and water buffer to each plant).Industry estimates that around 90% of media-based growers are in 'open' systems that free-drain their nutrient-rich wastewater to the environment, and it has been identified that wastewater products from hydroponic systems are potentially harmful to theenvironment and should be managed on farm.
