PROCESS AND APPARATUS FOR DISTRIBUTING COLD AMMONIA ABSTRACT OF THE DISCLOSURE An initial stream of cold liquid ammonia at substan- tially ambient or atmospheric pressure is divided into a plural- ity of smaller streams by directing the initial stream downward against a substantially horizontal and substantially flat surface, the axis of the initial stream being substantially orthogonal to the plane of the flat surface. The cold liquid ammonia is pref- erably produced by directing pressurized liquid ammonia into an expansion chamber to produce a mixture of cold liquid and gaseous ammonia at substantially ambient or atmospheric pressure and then separating the cold liquid ammonia from the cold gaseous ammonia. The divided cold liquid ammonia is preferably applied by a plural- ity of spaced conduits to the soil where the cold, liquid ammonia is then covered by additional soil by means of a field cultivator to prevent loss of ammonia to the atmosphere.
