Determination of salt out (crystallization) temperature of liquid fertilizers

Détermination de la température de désolubilisation (cristallisation) des engrais liquides

Abstract / scope

This document specifies the test procedure for the determination of the salt out temperature (SOT), also known as the crystallization temperature (CT) of liquid (fluid) fertilizers, using an inexpensive and simple technique.

This method might not be applicable to the binary and ternary fertilizers, especially with regards to the last crystal to disappear (LCTD). Some of these exceptions are discussed in the procedure (Clause 8).
