ABSTRACT:
A sprinkler system fertilization regulator is provided that automatically mixes a plurality of chemicals for the purpose of fertilization, weed control, or insect control. An electrically operated manifold distributes the chemical/water stream to each of the sprinkler zones provided. The output stream pressure is programmable, constant, and independent of the incoming fresh water pressure. Controls are provided for programming the relative percentage concentration of each of the constituent chemicals. Closed-loop fluid control systems are used throughout.
