ABSTRACT:
A fertilizer injection plow for underground fertilization by paste or liquid fertilizer. The plow, which is adapted for being mounted on a vehicle such as a tractor, carries one or more plowshares which are adjustable as to their depth of penetration into the soil. A fertilizer-containing drum is mounted on the plow for rotation by ground engagement as the plow travels. A fertilizer injection pump, driven by rotation of the drum, forces fertilizer to one or more nozzles disposed rearwardly of the plowshares.
