Single disc liquid fertilizer opener

ActiveUS20070044694A1Minimize opportunityEliminate premature mechanical failureTill seedingPlantingForce structureCircular disc
A method and apparatus to be mounted upon a planter row unit for delivering liquid fertilizer to the bottom of a trench without contacting the seed to be planted is disclosed and claimed. The system as claimed and described is adapted for mounting to substantially all modern row units employing floating row units. The method and apparatus as described does not interfere with existing down pressure or seed placement systems as found on modern row crop planters. As described and implemented, the method and apparatus is more compact and lighter in weight than the prior art. The attached assembly for a seed planting unit works in combination with a seed trench opener to form a trench for the deposit of liquid fertilizer offset from and parallel to the later formed seed trench. The apparatus allows directed liquid fertilizer delivery in close proximity to the seed trench with minimal disruption of said seed trench. The attachment includes a single disk blade disposed forward of the seed trench forming unit. The single disk blade is disposed at an angle of four degrees or less from the line defining the direction of travel of the seed planting implement in combination with a furrow strap. The attachment includes a selectively adjustable down force structure and a selectively adjustable depth control mechanism.
