Agricultural fertilizer applicator certification is required in Ohio for farmers who apply fertilizer to more than 50 acres of agricultural production grown primarily for sale. This requirement was signed into law in June 2014, and also requires certification for commercial agricultural fertilizer applicators. Farmers who have their fertilizer applied by co-ops or custom applicators are not required to be certified.

Applicators who are a Certified Crop Adviser (CCA) or Certified Livestock Manager (CLM) are not required to attend the training. Fertilizer is defined for the regulation as any substance containing nitrogen, phosphorus, potassium, or other plant nutrient in a dry or liquid formulation. All application types such as broadcast, side dress, sub-surface, knifing and other are included in the certification requirement. Lime and limestone are not included as fertilizer for the certification and farmers who only use starter fertilizer in their planter boxes are exempted.

The agriculture fertilizer certification is not required for manure applications, unless farmers are applying livestock or poultry manure from a Concentrated Animal Feeding Facility (CAFF). In this case, they would need to have either the CLM or Ohio Fertilizer Certification.

The Ohio Department of Agriculture is the agency issuing the certification for agriculture fertilizer applications. Once an applicator completes the fertilizer training, the ODA will bill them $30 for their fertilizer certificate unless the applicator currently holds a pesticide applicator license.

The ODA website has information regarding the regulation at agri.ohio.gov.  For more information about training sessions or general materials for the agriculture fertilizer certification, visit nutrienteducation.osu.edu or contact Dean Kreager, Licking County OSU Extension at kreager.5@osu.edu.
