ABSTRACT:
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 may be integrated with a cleaner for the furrow opening device. 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.
