Abstract: A fertilizer sprinkler system including a pipe system adapted for flow of liquid therethrough. The pipe system is comprised of an open inboard portion, a closed outboard portion and an intermediate portion. The inboard portion is coupled to a main water line. The intermediate portion is defined by a first vertical member, a horizontal member and a second vertical member. The intermediate portion further has a lower horizontal member having a first end in fluid communication with the first vertical member and a second end in fluid communication with the second vertical member. The lower horizontal member has an intermediate segment having an integral lid extending downwardly therefrom. The lid has an inlet port and an outlet port therethrough. A fertilizer container removably couples with the lid of the pipe system. A plurality of outlet valves are positioned within the outboard portion of the pipe system. The plurality of outlet valves are adapted for coupling with sprinklers.
