Fertilizer - Agricultural Fertilizer Applicator Certificate

Please download and complete the form using the "Download" button to the right.


This application required to issue new Agricultural Fertilizer Applicator certificates to people who do not have a Pesticide License. Renewal forms (to renew a current certificate for the next year) are different and are mailed by the Department when needed. For those who already have a Pesticide License, this form is not needed and you will be issued a license once their training or exam is completed.

The Agricultural Fertilizer Applicator certificate is for any individual who applies or supervises the application of a commercial fertilizer to more than 50 acres of 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. Please note: this certification is only required for those applying fertilizer to agricultural land; turf and other non-agricultural applicators are not required to have this certificate.

To prepare for the exam, the current Ohio Agricultural Fertilizer Applicator Certification Training Manual can be purchased from OSU here: https://extensionpubs.osu.edu/crops/field-crops/
