Abstract
An improved, stable, aqueous suspension fertilizer composition is provided containing from about 8 to about 75 weight percent monoammonium phosphate, from about 1 to about 6 weight percent ammonia, and from about 1 to about 3 weight percent clay. The composition has a total equivalent water content in the range of about 25 to about 60 weight percent. When desired, additional ingredients such as an aqueous urea-ammonium nitrate solution, having a nitrogen content of about 28 to about 32 percent, and potash can be employed. The composition is further characterized in that the mole ratio of ammonia to phosphoric acid equivalent is maintained in the range of from about 1.2:1 to about 1.8:1. The composition is produced by admixing the ingredients in an agitator-equipped mixing vessel for an effective period of time and under suitable agitation conditions to form a suspension.
