Who needs a fertilizer certification?: Fertilizer certification is required if you apply fertilizer (other than manure) to more than 50 acres used for agricultural production grown primarily for sale. If you have the co-op or other custom applicator make your fertilizer applications, you do not need the certification.
- What fertilizer is included in the certification?: Fertilizer is any substance containing nitrogen, phosphorus, potassium, or other plant nutrient in a dry or liquid formulation. All application types (broadcast, side dress, sub-surface, knifing, etc.) are included in the certification requirement. The only application exempted is start-up fertilizers that are applied through a planter. For this certification requirement, lime and limestone are not considered fertilizers.
- Who is exempt from the training requirement? Applicators who are a Certified Crop Advisor (CCA) or Ohio Certified Livestock Manager (CLM) are not required to attend training to become certified for fertilizer applications. However, those with a CCA or CLM exemption for training must still contact Ohio Department of Agriculture at 614-728-6987 to complete the exemption paperwork and pay for the fertilizer certification if the applicator does not already have a pesticide applicator license.
