An irrigation system has been designed and developed for the purpose of applying both water and chemicals through separate nozzle systems from the same basic moving pipe and tower structure. The primary objective of the dual nozzle system is for efficient irrigation along with very accurate application and total coverage of water conserving type chemicals such as antitranspirants, growth regulators, and soil surface evaporation suppressants. However, all chemicals currently being used in agricultural production may also be accurately applied through the system. Both nozzle systems are completely adjustable in the vertical and horizontal directions and are dynamically operated under the control of a programmable controller. The system is propelled with conventional 480-volt, 3-phase electric motors and moves with steady uniform motion.
