Patent Images
1. A method of making a fertilizer product, the method comprising steps of:
- providing a base fertilizer particle comprising at least one fertilizing component;
applying an inner coating to the fertilizer particle to form a fertilizer-additive particle, the inner coating comprising at least a first layer, wherein the first layer comprises at least one additive;
applying a water insoluble outer coating to the fertilizer-additive particle to form the fertilizer product, wherein the outer coating bonds to the inner coating and maintains the inner coating on the base fertilizer particle until the base fertilizer particle undergoes dissolution and releases the fertilizing component.
