Abstract
A fertilizer composition including a base fertilizer granule with a barrier coating and one or more micronutrients. The base fertilizer material is coated with a barrier coating, and then a coating of one or more micronutrients. Alternatively, the base fertilizer material is coated with a barrier coating having discrete particles of micronutrients dispersed throughout. The barrier coating acts to physically and chemically isolate the micronutrient particles from the underlying fertilizer composition such that more of the micronutrient is available to the soil solution, and ultimately to the root zone of the plant.
Claims25
A fertilizer composition comprising:
- a base fertilizer granule;
- a barrier coating covering at least a portion of an outer surface of the base fertilizer granule;
- and
- one or more micronutrients covering at least portion of the barrier coating such that the one or more micronutrients are isolated from the base fertilizer granule.
A fertilizer composition comprising:
- a base fertilizer granule;
- a barrier coating covering at least a portion of an outer surface of the base fertilizer granule;
- and
