First Claim
1. A fertilizer knife apparatus comprising:
- a planter;
a housing attached to a front portion of said planter;
a fertilizer knife for making a slot in the ground;
adjustable means operably attached to said housing and to said fertilizer knife for permitting said knife to be adjusted vertically with respect to said housing;
pivot means for operably attaching said fertilizer knife to said adjusting means for permitting said fertilizer knife to pivot about a substantially vertical axis, whereby the fertilizer knife will accurately track in front of a line into which seeds are to be planted, and which will tend to be deflected temporarily when rocks or other potentially damaging obstructions are encountered;
said knife having a leading edge extending from a point in close proximity to said pivot means, downwardly and rearwardly therefrom, said knife also having an extreme rear edge thereof; and
conduit means attached to said extreme rear end of said knife for delivering liquid fertilizer to said slot in the ground including means for attachment to a source of liquid fertilizer at the top thereof and leading to a discharge opening near the bottom thereof whereby the liquid fertilizer will be discharged into said slot formed in the ground by the knife without destroying the basic configuration of said slot in the ground.

Abstract
A fertilizer knife adapted to be attached to a planter. A housing is adjustably attached to the fertilizer knife and an adjustable mechanism is provided for permitting the knife to be adjusted vertically with respect to the housing, thereby adjusting the effective depth that the fertilizer, in a liquid form, will be released. The fertilizer knife is attached to the housing whereby the fertilizer knife will accurately track in front of the line into which the seeds are being planted, and this pivoting feature will also permit fertilizer knife to be deflected to one side or the other temporarily when rocks or other potentially damaging obstructions are encountered. The fertilizer knife has a leading edge extending from a point in close proximity to a vertical pivotal axis, and tapers downwardly and rearwardly therefrom.
