Abstract

The fertilizer dispenser of the present invention comprises a tank having an elliptical shape and being disposed vertically with respect to its rectilinear axis on a suitable pedestal; a bladder made of a flexible, resilient material disposed within the tank and fastened to the lowermost interior end wall of the tank; a column disposed into the bladder from the lowermost interior end wall of the tank to a point distally from the uppermost terminal end of the tank; a fertilizer input tube operable to conduct fluid fertilizer under pressure from a suitable source to the lowermost terminal end of the tank into the bladder; a fertilizer output tube operable to conduct the fertilizer from the bladder and the tank into an irrigation water supply pipe; and a water governor tube operable to conduct water under pressure from the pipe to the interior walls of the tank and outside the bladder. The column may be made of an open mesh screen disposed about the connections of the fertilizer input tube and the fertilizer output tube.

Claims

1. A fertilizer dispenser, comprising a tank having an elliptical shape disposed vertically with respect to its rectilinear axis on a suitable pedestal;

a bladder made of flexible, resilient material disposed within said tank and fastened to the lowermost interior end wall of said tank;

a column disposed into said bladder from the lowermost interior end wall of said tank to a point distally from the uppermost terminal wall of said tank;

a fertilizer input tube operable to conduct fluid fertilizer under pressure from a suitable source to the lowermost terminal end of said tank into said bladder;

a fertilizer output tube operable to conduct said fertilizer from said bladder and said tank into an irrigation water supply pipe; and

a water governor tube operable to conduct water under pressure from said pipe to the interior walls of said tank and outside said bladder.

2. The apparatus of claim 1, wherein the column includes open mesh cylindrical walls, and a pedestal connecting the lowermost terminal end of said column to said lowermost interior end wall of said tank, said pedestal operable to fasten said bladder to said tank and encircle the connection of said fertilizer input tube and the connection of said fertilizer output tube with said tank.

3. The apparatus of claim 1, wherein said water governor includes a cone-shaped jam disposed distally within said pipe, said jam having its widest end disposed in the direction from which the irrigation water is traveling;

and wherein said fertilizer output tube includes an orifice disposed distally within said pipe, said orifice having its exitway disposed in the direction in which said irrigation water is traveling.
