Abstract
A microprocessor (220), disposed in an irrigation controller (200), is programmed to automatically derive an irrigation schedule based at least in part on a rolling-average of required watering amounts. The rolling-average is preferably an average of four consecutive required watering amounts but may be more or less than four. Preferably the irrigation schedule and required watering amount are at least partly derived from ETo data. The ETo data may include potential ETo data, estimated ETo data, or historical ETo data.
