Center-pivot irrigation

Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of <a href="/facts/Agriculture/TGztqzJs">crop</a> <a href="/facts/Irrigation/RWX5PEgK">irrigation</a> in which equipment rotates around a pivot and crops are watered with <a href="/facts/Irrigation_sprinkler/ttgK7IDB">sprinklers</a>. A <a href="/facts/Circle/9fy5ggKn">circular</a> area centered on the pivot is irrigated, often creating a circular pattern in crops when viewed from above (sometimes referred to as crop circles, not to be confused with <a href="/facts/Crop_circle/AxVIpLn8">those</a> formed by circular flattening of a section of a crop in a field). Most center pivots were initially water-powered, however today most are propelled by <a href="/facts/Electric_motor/ArD7BGDa">electric motors</a>. 
Center-pivot irrigation systems are beneficial due to their ability to efficiently use water and optimize a farm's yield. The systems are highly effective on large land fields.
