Cold flow liquid vapor shoe
First Claim
1. A shoe for use with an earth plow having at least one chisel blade mounted upon a chisel shank and adapted to move through field earth so as to create a trench, the shoe comprising means for applying and at least temporarily holding ammonia in the soil, the means including, a vapor tube for receiving ammonia vapor, a vapor tube orifice defined in the vapor tube for dispensing the received ammonia vapor, a liquid tube for receiving ammonia liquid, and a liquid tube orifice defined in the liquid tube and located above and to the rear of the vapor tube orifice for dispensing liquid ammonia in a path that intersects from above the path of discharge of the previously dispensed ammonia vapor as the plow chisel moves through the ground and forms the trench, so as to encourage the liquid ammonia to act as a fluid blanket to the ammonia vapor and to discourage vapor escape from the trench before the liquid and vaporous ammonia are covered by field earth.

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.

- 10. A tool for plowing and fertilizing an earthen field, comprising, in combination, a frame adapted to move over the field, at least one chisel shank depending from the frame, a chisel blade detachably secured to the chisel shank for moving through the earth and thereby forming a trench, and a shoe attached behind the blade and shank for dispensing ammonia fertilizer into the chisel trench, the shoe comprising means for applying and at least temporarily holding ammonia in the soil, the means including a vapor tube for receiving ammonia vapor, a vapor tube orifice formed in the rear of the vapor tube for dispensing ammonia vapor rearwardly of the chisel and tube into the trench, an ammonia liquid tube affixed to the rear of the vapor tube, and a liquid tube orifice formed in the bottom of the liquid tube and located above the vapor tube orifice for dispensing liquid ammonia in a path that intersects from above the path of discharge of the dispensed ammonia vapor into the trench to encourage ammonia retention in the trench.
