Abstract

Liquid fertilizer compositions and methods of making liquid fertilizer compositions are set forth herein. In one embodiment, a liquid fertilizing composition includes an aqueous ammonium chloride solution having a pH between 6.5 and 8.5, a dispersant selected from anionic polyacrylamides, and a corrosion inhibitor. In another embodiment, a liquid fertilizing composition includes an aqueous solution having a pH between 6.5 and 8.5. The solution includes at least 16.5 percent by weight of ammonium chloride and between 0.5 and 1.0 percent by weight of dispersant. In yet another embodiment, a liquid fertilizing composition has a pH between 7.5 and 8.5. The composition consists essentially of at least 16.5 percent by weight ammonium chloride, between 0.5 and 1.0 percent by weight dispersant, an effective amount of corrosion inhibitor, and water.
