This is an estimated temperature at which a fertilizer or a fertilizer mixture begins to form crystals and salt out from suspension. It is dependent on many factors, including the products mixed, the purity of the products mixed, temperature, water content, etc. The math the program uses comes directly from the TVA blend models on liquid fertilizer blends. These models were developed from laboratory studies using highly pure products. The users’ own experiences in working with the existing products will assist in refining the users’ expectations for the results of these models.
