AbstractWater conservation in metropolitan areas of Arizona is critical if limited water resources are to meet current and future demands. Timer controlled landscape irrigation systems contribute to a large portion of municipal water use, and there is currently a great potential for water savings when deficit irrigation is practiced. Such systems tend to forfeit deficit irrigation by overwatering vegetation; however, deficit irrigation may be improved if the number of irrigation cycles are reduced based on sensing soil water in the plant root zone. A patent pending electronic circuit, called the overwatering controller, has been developed and tested for this purpose. Test results show the overwatering controller has great potential as a water conservation and deficit irrigation management tool.
