Water 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 a great potential for water savings if deficit irrigation is practiced. The overwatering controller used in this research senses soil water and prevents irrigation if sufficient water is in the soil. The controller was evaluated at 50 sites in Tucson, Arizona. An average of 35% water savings was observed and 30% of irrigation cycles were skipped.
