Measured Irrigation

Measured irrigation is a significant step forward in water conservation – it  allows farmers freedom to pursue other income generation activities while produce is irrigated automatically.

What is measured irrigation?

 For conventional pressurised irrigation systems, the volume of water delivered to a plant during the irrigation event depends upon the flow rate. But for measured irrigation the volume of water delivered to a plant during the irrigation event is independent of the flow rate.

 An irrigation system that is independent of the flow rate is a potential threat to multinational irrigation companies that have billions of dollars invested in pressurised irrigation technology. It is not surprising therefore that no irrigation company worldwide has so far shown any interest in measured irrigation. If you are interested in measured irrigation you are unlikely to receive any encouragement or support from the irrigation industry.

 Measured irrigation allows you to decide how much water will be delivered to each plant in your garden. Hence you know in advance the total volume of water that will be used.

  • A 20 watt solar panel provides enough power to irrigate 200 sqm at 10 litres per sqm.

  • Measured irrigation is completely automatic with the irrigation frequency proportional to the prevailing evaporation rate. Furthermore, whenever it rains the start of irrigation is delayed.

  • Measured irrigation is usually gravity feed and does not require access to mains water or mains power and so there are no ongoing costs for mains water or electricity.

  • Measured irrigation may be well suited to small landholders in poorer countries where access to mains power and mains water is either unreliable or too expensive. In remote locations where mains power and mains water are unavailable, measured irrigation can provide an automated irrigation system that can deliver measured volumes of water to each plant.
