Center-pivot irrigation (sometimes called central pivot irrigation), also called circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers. A circular area centered on the pivot is irrigated, often creating a circular pattern in crops when viewed from above (sometimes referred to as crop circles). Most center pivots were initially water-powered, and today most are propelled by electric motors.
Elaborate combination of different sprinklers makes the water better distributed, advancing the efficiency of irrigation. Both the low-pressure deflector type spray nozzle and Rotator are with high wind resistance and meet the requirements even in windy conditions.
