Abstract
A fluid fertilizer composition based essentially on potassium chloride and an ammonium phosphate prepared by a process which comprises comminuting a solid substance containing potassium chloride and ammonium phosphate by grinding in the presence of a saturated solution of solid in a liquid in which the solid has a solubility greater than 1% by weight, the mixture of the solution and the solid being in fluid condition with the solid being a separate phase during grinding and the solution having dissolved therein an additive which is a crystal growth inhibitor for the solid whereby crystal growth is inhibited at both existing crystal surfaces and new crystal surfaces created by the breaking down of relatively coarse particles.
