Abstract: Apparatus for adding liquid fertilizer to a water line of a sprinkler system includes a mechanical injector device powered by a paddle wheel turned by water flowing through the water line. The mechanical injector device includes a plunger that moves back and forth in the plunger chamber. Movement in one direction allows liquid fertilizer from a liquid fertilizer reservoir to flow into the plunger chamber and movement of the plunger in the opposite direction injects the liquid fertilizer from the plunger chamber into the water. The mechanical injector device is coupled to the paddle wheel which causes movement of the plunger in the plunger chamber in at least one direction. Spring bias can cause movement of the plunger in the other direction. The mechanical injector device can be disabled to stop fertilizer injection while still allowing rotation of the paddle wheel.

Abstract: An apparatus for adding fertilizer to water flowing in an underground sprinkler system includes a pressure chamber with a bladder therein which holds liquid fertilizer. Water under line pressure surrounds the bladder in the chamber to pressurize the bladder and fertilizer therein. The pressurized liquid fertilizer flows from the bladder through a valve such as a needle valve which controls flow rate and through a valve such as a butterfly valve which opens to allow fertilizer flow when water flows through the line to which the fertilizer is to be added. With no flow of water, the valve is closed to prevent flow of fertilizer. The lid to the opening to the inside of the bladder used to fill the bladder with fertilizer is arranged to operate two valves. One controls flow of pressurized line water into the chamber to pressurize the bladder in the chamber when the lid is opened and the other opens a drain to depressurize the chamber when the lid is opened to allow fertilizer to be added to the bladder.
