An automatic fertilizer system apparatus having a liquid fertilizer dispenser for introducing the continuous addition of a selected amount of fertilizer, insecticide, herbicide type chemicals to sprinklers that use an outside waterline. The dispenser having an adjustable metering cap with different diameter through-holes for allowing the contents of the dispenser to be injected into the flowing stream of water which leads to the sprinklers in a selected precise manner. The system splits incoming water into the dispenser, and underneath the dispenser where an orifice having a inwardly facing bevelled through-hole along with the metering cap forms a point of lowest pressure region where the chemicals are injected into an output fluid flow to sprinkler heads in amounts selected and dependent upon by the different sized metering caps.

[ We claim:] [14.] An automatic fertilizing apparatus comprising:means for introducing a fluid flow from a fluid flow source;a first splitter having a first side opening, a top opening, and a second side opening, the first side opening for receiving the fluid flow and separating the fluid flow into a first fluid path through the top opening and into a second fluid path through the second side opening;a main body housing a chemical liquid, the main body having a first opening in an upper portion of the main body for receiving the chemical liquid therein, a second opening in the upper portion of the main body for receiving the first fluid path and providing a fluid flow path to an interior portion of the main body beneath the chemical liquid for raising the chemical liquid, and a bottom opening in the main body;a metering cap attached to a pipe within the main body for preselecting the amount of the raised chemical liquid that passes to the bottom opening, the metering cap having a variable sized diameter through-hole thereof, the variable sized diameter through-hole being equivalent to a preselected amount of the chemical liquid to be mixed with the fluid flow, the metering cap and the pipe forming a chemical liquid path to the bottom opening;a second splitter having a first side opening, a top opening and a second side opening, the first side opening for receiving the second fluid path, a top opening connected to the bottom opening of the main body for receiving the chemical liquid path, the second side opening connected to an output line;an obstruction means having a central orifice through-hole, the obstruction means positioned between the first side opening of the second splitter and the second side opening of the first splitter, wherein the obstruction means causes a pressure differential on both sides thereof with a point of lowest pressure within the second splitter, and the metering means controlling the preselected amounts of the chemical liquid being injected into the output line.
