Research abstract
Application of chemicals with irrigation water is a widely adopted practice with center pivot irrigation systems, however, the standard practice of chemical injection at a constant rate results in systematic chemical application errors ranging from 7 to 22% for center pivots equipped with a corner watering attachment and/or an end gun. This project evaluates the feasibility of a less expensive and more reliable means to control flow proportional chemical injection with center pivot systems than currently commercially available to reduce systematic chemical application errors.
