Center pivot irrigation systems are designed and managed to apply water as uniformly as possible to enhance crop production. Uniformity has a direct effect on the system’s overall application efficiency, which is a measure of how well an irrigation system delivers water to a crop’s root zone.
As planting progresses across the state, it is recommended that irrigators start installing water sensors in fields as time allows. Any time sensors are installed, a few simple questions should be addressed to ensure accurate readings for irrigation management later this season.
