Agricultural fertilizer applicator certification is required for farmers who apply fertilizer to more than 50 acres of agricultural production grown primarily for sale. Farmers who have their fertilizer applied by co-ops or custom applicators are not required to be certified.  Those who have a pesticide applicator license need to attend a two-hour fertilizer certification. If an applicator does not have a pesticide license, they will be required to attend a three-hour fertilizer certification.
