    Abstract: A process is disclosed wherein the precipitate formed during storage of a liquid phosphate-based fertilizer is removed by addition of phosphoric acid in an amount sufficient to form a solution thereof having a pH of less than about 3.2. Thereafter by pH adjustment such that there is provided a solution having a pH of 5.0 to 6.6, there is obtained a solution of the originally precipitated material which is in a form to be useful as a fertilizer.
