The present disclosure entails a program controlled multi-loop system for providing even distribution of irrigating water over normally square plots. More specifically the disclosure includes control loops connected to a center post irrigation system which control the advance rate, the flow rate, select an end gun nozzle, and select the elevation of the end gun under program control to provide even coverage. In this manner a telescopically extended system of the type described in our prior U.S. Pat. No. 4,033,508 is improved to both insure even irrigation and full coverage of corners.

In a center post irrigation system including a telescoping extension supported on a steerable carriage for pivotal translation, the improvement comprising: angular measuring means attached to said irrigation system for providing an angular signal indicative of the pivotal advance thereof; angular rate control means connected to said irrigation system and adapted to receive said angular signal for controlling the angular rate of said system in response thereto; a rotatable turret mounted on the end of said telescopic extension including a plurality of radially disposed nozzles each selectively aligned with said end; and pressure control means mounted in said extension for regulating the pressure of liquids propagated therethrough in response to said angular signal.
