Description of practice
Pivot irrigation is a method of overhead crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers. An area centred on the pivot is irrigated, often creating a circular pattern in crops when viewed from above.
|Examples of how to use pivot irrigation
(see Note below)
Irrigation pipe and sprinklers rotate round a central pivot which supplies the water. The system is used in large relatively flat fields.
A lateral-move irrigation system is configured to move in a straight line and water is supplied by an irrigation channel running the length of the field. While suited to rectangular fields, it requires complex guiding systems.
End gun pivot irrigation
Water guns attached to the ends of a pivot system are used to effectively irrigate additional land. Relatively high pressure is needed to supply the guns with enough water.
