A fertilization system may include a flow diverter to divert a portion of water from a ground irrigation system through a tank containing fertilizer and back into the ground irrigation system by creating a high pressure region up stream of the flow diverter and a low pressure region down stream of the flow diverter to provide hydraulic operation of the fertilization system.

Embodiments of the present disclosure include a valve assembly including a supply housing with a first bore and an injectable housing coupled to the supply housing with a second bore. The valve assembly further includes a piston extending through at least a portion of the first and second bores, the piston being reciprocable axially along a longitudinal axis. The valve assembly also includes a first inlet at a first end of the supply housing for directing a working fluid toward a first end of the piston. The valve assembly includes a second inlet extending through the injectable housing toward a cavity that receives an injectable material. The valve assembly also includes a second outlet at a second end of the injectable housing that directs the injectable material out of the injectable housing as the piston moves axially along the longitudinal axis.
