ABSTRACT:
An implement is provided for applying ammonia to the ground including a nurse tank feeding individual converters on each ground-working plow with each converter having an expansion cannister into which the gas is fed at the top and from which liquid is discharged from the bottom through a liquid outlet opening and fed to the ground. A plurality of baffles divide each expansion cannister into a plurality of expansion chambers. The liquid outlet openings of the cannisters are positioned above and adjacent the ground-working lower end portions of the respective ground plows to minimize the travel distance of depressurized liquid ammonia from the outlet openings to the ground. Each cannister is further provided with a vent opening for discharging ammonia vapor to the ground, the size of the vent opening being related to the volume of the cannister such that cold liquid ammonia will be discharged from the liquid outlet opening at approximately 2-4 psi. A liquid conduit in communication with the liquid outlet opening terminates behind and closely adjacent the lower end portion of the respective ground plow.
