Key:irrigated

The key irrigated=* is added to an area, usually landuse=farmland, to specify that it is irrigated land. To irrigate is to water plants by bringing in water from pipes, canals, sprinklers, or other man-made means, rather than relying on rainfall alone.

• irrigated=yes is used when the feature is irrigated.
• irrigated=no can be used with an area which is not irrigated, when this would usually be expected (for example, an area used to grown dryland rice instead of a flooded rice paddy).

See also irrigation=pivot which is also used to specify that an area of landuse=farmland or landuse=orchard is irrigated via a center-pivot irrigation system with sprinklers.
