A new method for managing irrigation with UAS may be easier and more effective than anything used by farmers today.
It’s designed to solve a pressing problem for California orange farmers: getting the coveted “Fancy” quality classification for their fruit. Left at a constant irrigation level, some orange varieties will develop creases that make them worthless for anything but juicing, so farmers must temporarily restrict water levels throughout the season, testing trees periodically to see how much water they’re receiving.
