Abstract:

A liquid fertilizer injector system attached to a water source by a water source has an inlet line to input the water from the water source line into the liquid fertilizer injector system. The system's components include a holding tank to receive the water from the inlet line, a collapsible impermeable bag that is filled with liquid fertilizer and is placed in the holding tank, the water from the inlet line collecting in the holding tank and exerting pressure on the collapsible impermeable bag as it collects in the holding tank, an outlet line to disperse the liquid fertilizer back to the water source line, a port position indicator valve on the outlet line, to incrementally control the flow of liquid fertilizer from the outlet line back to the water source line, and a drainage valve to drain any input water in the holding tank.
