ABSTRACT
Chemigation uniformity means that all areas of the fi eld serviced by the micro irrigation system receive the same amount of chemical during an injection event. While there may be times when we want to intentionally apply different amounts of chemical to various portions of the fi eld, it takes a very sophisticated micro irrigation injection system to achieve that. In the vast majority of cases, our goal is to apply the injected chemical uniformly as the water is applied. High chemigation uniformity requires:
(1) An irrigation system with high application uniformity; and (2) An injection system that facilitates high chemigation uniformity. Well-
The injection system, especially the injector, is a critical piece of hardware necessary to achieve high chemigation uniformity.
