Abstract: Apparatus for dividing a gravity flow liquid stream into a plurality of separate streams of predetermined proportions comprising (a) a substantially vertical inner liquid inlet tube having a closed end, such end being that toward which the liquid is flowing, and this inner tube containing one or more substantially parallel vertically elongated openings beginning at the closed end of the tube, such openings being of such size as to cause a partial backup of liquid traveling toward the end of the tube; (b) a substantially vertical covering tube having a closed end and containing a plurality of substantially parallel vertically elongated openings, but offset from the vertically elongated opening or openings of the inner tube, and wherein the space between the inner surface of the covering tube and the outer surface of the inner tube, and the size of the vertical opening of the covering tube are such that a partial backup of liquid occurs between the inner tube and the covering tube; and (c) outlet means for coll

Abstract: An initial stream of cold liquid ammonia at substantially ambient or atmospheric pressure is divided into a plurality 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 preferably 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 plurality 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.

Abstract: Cold ammonia, preferably cold liquid anhydrous ammonia preferably at substantially ambient or atmospheric pressure, is applied (1) to the soil as a fertilizer or (2) to feed grains, forages and anaerobically fermentable plant material to supply thereto and provide therein non-protein nitrogen (NPN).
