ABSTRACT:
Substantially dried free flowing micronutrient compositions having up to 15% by weight of a micronutrient, a binder, and a densifying agent are produced according to the invention. The process for producing the compositions includes the steps of dissolving or dispersing up to approximately 15% by weight of the micronutrient and a binding amount of a binder in water to obtain an aqueous mixture; suspending a densifying amount of a solid densifying agent in the mixture, the densifying agent having a particle size of approximately 40 mesh to approximately 325 mesh; and spray drying the suspension to produce the micronutrient composition.
