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.

A method for automating application of a chemical to a target through a liquid dispenser having a dosage cycle during which liquid is dispensed therefrom, the chemical being provided by a solid chemical source, the liquid dispenser being coupled to a liquid source providing at least a portion of the liquid, the target having a target area, the method comprising: determining an amount of the chemical to be applied to the target, based on the target area; receiving a mixing liquid from the liquid source; applying the mixing liquid to the solid chemical source to create a sump mixture containing the mixing liquid and the amount of the chemical and calibrating the sump mixture to adjust a concentration of the sump mixture, wherein the calibrating step comprises performing the calibration using a calorimetric system; and distributing, during at least a portion of at least one run time of a sprinkler control system, the sump mixture flowing through the liquid dispenser to an output of the sprinkler control system, wherein the sump mixture is mixed with the output of the sprinkler control system and is delivered via the sprinkler control system to the target. 3. A method for automating application of a chemical to a target through a liquid dispenser having a dosage cycle during which liquid is dispensed therefrom, the chemical being provided by a solid chemical source, the liquid dispenser being coupled to a liquid source providing at least a portion of the liquid, the target having a target area, the method comprising: determining an amount of the chemical to be applied to the target, based on the target area; receiving a mixing liquid from the liquid source; applying the mixing liquid to the solid chemical source to create a sump mixture containing the mixing liquid and the amount of the chemical and calibrating the sump mixture to adjust a concentration of the sump mixture, wherein the calibrating step comprises performing the calibration using a conductivity system; and distributing, during at least a portion of at least one run time of a sprinkler control system, the sump mixture flowing through the liquid dispenser to an output of the sprinkler control system, wherein the sump mixture is mixed with the output of the sprinkler control system and is delivered via the sprinkler control system to the target. 4. A method for automating application of a chemical to a target through a liquid dispenser having a dosage cycle during which liquid is dispensed therefrom, the chemical being provided by a solid chemical source, the liquid dispenser being coupled to a liquid source providing at least a portion of the liquid, the target having a target area, the method comprising: determining an amount of the chemical to be applied to the target, based on the target area, and dividing the target into a plurality of zones; receiving a mixing liquid from the liquid source; applying the mixing liquid to the solid chemical source to create a sump mixture containing the mixing liquid and the amount of the chemical; and distributing, during at least a portion of at least one run time of a sprinkler control system, the sump mixture flowing through the liquid dispenser to an output of the sprinkler control system, wherein the sump mixture is mixed with the output of the sprinkler control system and is delivered via the sprinkler control system to the target, wherein the distributing step further comprises: measuring the run time for each of the plurality of zones; defining the dosage cycle based on the run time; and dispensing the sump mixture within the dosage cycle. 5. The method of claim 4, wherein the distributing step further comprises positioning the dosage cycle as a specific portion of the run time. 6. The method of claim 4, wherein the determining step further comprises tailoring the sump mixture based on the specific needs of each of the plurality of zones. 7. The method of claim 4, further comprising adjusting the sump mixture based on input from at least one add-on component. 8. The method of claim 4, wherein the determining step further comprises comparing a total previous application amount to a desired application amount to formulate the sump mixture. 9. The method of claim 4, wherein the determining step further comprises: selecting from a plurality of chemicals; and accessing data relevant to each of the plurality of chemicals. 10. The method of claim 9, wherein the selecting step further comprises mixing two or more of the plurality of chemicals. 11. An automatic chemical application system for automating application of a chemical to a target through a liquid dispenser having a dosage cycle during which liquid is dispensed therefrom, the chemical being provided by a solid chemical source, the liquid dispenser being coupled to a liquid source providing at least a portion of the liquid, the target having a target area, the system comprising: a computing module that determines an amount of the chemical to be applied to the target, based on the target area; a mixing module coupled to the computing module that receives a mixing liquid from the liquid source and applies the mixing liquid to the solid chemical source to create a sump mixture containing the mixing liquid and the amount of the chemical; and a dispensing module coupled to the mixing module and a sprinkler control system, wherein the dispensing module distributes, during at least a portion of at least one run time of the sprinkler control system, the sump mixture through the liquid dispenser to an output of the sprinkler control system, wherein the sump mixture is mixed with the output of the sprinkler control system and is delivered via the sprinkler control system to the target. 12. The system of claim 11, further comprising an application module coupled to the mixing module, wherein the application module calculates a total previous application amount, compares the total previous application amount and a desired application amount, and automatically adjusts the mixture application amount based on the comparison. 13. The system of claim 12, wherein the application module maintains the total previous application amount for a given duration. 14. The system of claim 11, wherein the target is divided into a plurality of zones. 15.
