Abstract
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.
