Abstract
Abstract FREE-FLOWING AND UNIFORM MICRONUTRIENT ENRICHED FERTILIZER COMPOSITIONS ARE PROVIDED. THE COMPOSITIONS INCLUDE A GRANULAR FERTILIZER, UP TO ABOUT 20% BY WEIGHT OF A FINELY DIVIDED MICRONUTRIENT, AND AN AQUEOUS ZINC CHLORIDE BINDER SOLUTION. THE ZINC CHLORIDE BINDER IS PRESENT IN AN AMOUNT SUFFICIENT TO BIND THE MICRONUTRIENT TO THE SURFACE OF THE FERTILIZER GRANULES WITHOUT DESTROYING THE FERTILIZER''S FREE-FLOWING PROPERTIES. THE COMPOSITIONS ARE PREPARED BY FIRST MOISTENING THE SURFACES OF THE FERTILIZER GRANULES WITH THE BINDER AND THEN MIXING THE MICRONUTRIENT WITH THE MOISTENED GRANULES UNTIL ADHESION IS SUBSTANTIALLY COMPLETE.
