ABSTRACT:
An automated chemical application system for automating the application of a chemical to a target. In a first embodiment, an automated chemical application system connects to and interacts with an individual's existing sprinkler system. The automated chemical application system may thereby deliver concentrations of agricultural chemicals to different zones of the lawn via the sprinkler system. In a second exemplary embodiment, an automated chemical application system automatically mixes a chemical with water to dispense a precise amount of the chemical to a target.
