Who needs the agricultural fertilizer certification?
Fertilizer certification is required if you apply fertilizer (other than manure) to more than 50 acres of agricultural production grown primarily for sale. If you hire a co-op or other custom applicator to make your fertilizer applications, you do not need the certification.
