Abstract

A liquid fertilizer application system for efficiently dispensing and placing liquid fertilizer within a furrow to minimize germination injury. The liquid fertilizer application system includes a guard with an attached fertilizer tube having an input opening and a discharge opening. The discharge opening of the fertilizer tube is attached in front of the guard used to protect the implement seed tube. The discharge opening of the fertilizer tube forward of the seed tube allows for the application of the fertilizer into the prepared furrow prior to placement of the seed.

Claims

1. A fertilizer applicator, comprising:

a guard attached to a shank of a planter, wherein said guard has a front end and a rear end; and

a fertilizer tube including an input opening to receive a flow of fertilizer and a discharge opening for dispensing said flow of fertilizer;

wherein said fertilizer tube is comprised of an elongated tubular structure;

wherein said fertilizer tube is attached to said front end of said guard;

wherein said fertilizer tube includes a first segment, a second segment, a third segment, a fourth segment and a fifth segment;

wherein said fifth segment is attached to said front end of said guard;

wherein said discharge opening is positioned within said fifth segment;

wherein said discharge opening is at a bottom end of said fertilizer tube;

wherein said fifth segment extends forwardly and upwardly with respect to said guard;

wherein said fourth segment extends forwardly from said fifth segment opposite of said discharge opening in a horizontal manner;

wherein said third segment extends forwardly and upwardly from said fourth segment opposite of said fifth segment;

wherein said second segment extends rearwardly and upwardly from said third segment;

wherein said first segment extends rearwardly and upwardly from said second segment;

wherein said first segment extends upwardly at an angle less than said second segment with respect to a horizontal plane;

wherein said input opening is positioned within said first segment;

wherein said input opening is at an upper end of said fertilizer tube;

wherein said first segment is positioned above said second segment, said third segment, said fourth segment and said fifth segment;

wherein said second segment is positioned above said third segment, said fourth segment and said fifth segment;

wherein said third segment is positioned above said fourth segment and said fifth segment;

wherein said fourth segment is positioned above said fifth segment.

2. The fertilizer applicator of claim 1, including a tab extending substantially transversely from said third segment.

3. The fertilizer applicator of claim 2, wherein said tab is welded to said third segment of said fertilizer tube.

4. The fertilizer applicator of claim 2, wherein said attached tab is welded substantially perpendicular to said guard.

5. The fertilizer applicator of claim 2, wherein said tab is comprised of a flat and straight structure.

6. The fertilizer applicator of claim 2, wherein said fertilizer tube is welded to said front end of said guard.
