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. We have limited the equipment described here to those products with agents and backup within Australia. The hub of the publication is a collection of tables summarising the main product features. This enables you to compare product features. As well as technical data, there is also commercial information on suppliers, contact details, availability and price (accurate at August, 2000). Case studies from personal experience and from the literature provide further insight into the advantages and limitations of each device in relation to its potential applications.
