ABSTRACT:
A system for programming and controlling the rate at which an agricultural chemcial (e.g., fertilizer) is supplied to the water in an agricultural irrigation system. In one embodiment the system is combined with a center pivot irrigation system having a vertical water feed pipe, a horizontal boom, and a chemical supply connected to the feed pipe. A rotation sensor determines the degree of rotation of the boom and a controller controls the amount of chemical supplied to the feed pipe. The system enables the amount of chemical applied to be varied from one section of a field to another.
