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.
