ABSTRACT:
A fertilizer applicator is provided for use with a sprinkler line system. The applicator comprises a fertilizer container with integrally formed internal inlet and outlet tubes. Water is fed through an inlet-outlet tube into the bottom of the fertilizer container, where it dissolves or dilutes some of the solid or liquid fertilizer and forms a leached, concentrated solution. This concentrate continuously rises through the fertilizer and into the outlet tube where it drains downwardly. The concentrate is then diluted with water coming through the inlet-outlet tube including a venturi, the size of which controls the flow rate of the concentrate. The diluted concentrate is then passed into the sprinkler system for application to vegetation. The applicator has a single piece, simplified design, without moving parts, and does not leak fertilizer into the drain. Also, the bore arrangement of the applicator enables the device to be drained and then filled with fertilizer, without fertilizer leakage, followed by running water through the fertilizer at any selected time, and this renders the operation more automatic.
