Abstract
An irrigation system is disclosed which includes a center pivot support having an elongated main water boom pivotally connected thereto which extends outwardly therefrom. An elongated extension boom is pivotally connected at its inner end to the outer end of the main boom and is supported by a steerable drive tower. A corner arm sensor is provided for sensing the angle of the extension boom with respect to the main boom. A plurality of sprinklers are positioned on the extension boom along the length thereof and are controlled by a computer which is programmed with a table of sprinkler sequences. The computer calculates the areas being covered by the extension boom as the system is moved through the field and determines the best sprinkler sequence for the sprinkler on the extension boom.
