ABSTRACT:
A chisel plow and a cold flow shoe for dispensing ammonia fertilizer into an earthen field are disclosed. The shoe includes a vapor tube for receiving ammonia vapor, and a liquid tube for receiving ammonia liquid from sources which can be mounted upon the plow. The vapor tube defines an orifice for dispensing the received ammonia vapor in a rearward direction into a trench formed by the plow chisel. The liquid tube defines a liquid dispenser orifice located immediately above and to the rear of the vapor dispensing orifice. Liquid ammonia is thus dispensed atop the previously dispensed ammonia vapor as the plow chisel moves through the ground and forms the trench. As earth collapses atop the dispensed ammonia, the ammonia is retained in positions located immediately adjacent growing crop plants, or adjacent those locations where plants will be grown. Effective, efficient ammonia fertilization is thus provided.
