Abstract: A fertilizer injector comprising in combination a fertilizer storage hopper having an offset bottom portion, an elongated tubular centralizer offset from the hopper and in axial alignment with the bottom portion, an injector-rod mounted in the tubular centralizer and bottom portion, whereby downward movement of the injector rod forms a hole of selected depth in the surface of the soil and upward movement of the injector rod allows a selected quantity of granular fertilizer to fill the hole and another downward movement closes off an outlet in the offset bottom portion stopping the flow of fertilizer from the hopper, and a means for locking the injector rod in any desired position. The fertilizer injector also has a filter screen and lid to prevent undesirable material from entering the hopper.
