Agricultural Fertilizer Applicator

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 yourself.

Under this certification program, commercial fertilizers do NOT include lime, limestone, marl, underground bone, water, residual from farm products, animal or vegetable manures, unless mixed with fertilizer materials or distributed with a guaranteed analysis. 

For New or Expired Certificates

If you wish to get a new AFA certificate, or if your previous certificate has been expired for more than 180 days, then you will need to either:

  • Attend a 3 hour training class, or 
  • Pass the exam

Find a 3 hour training class

At the end of the training class or exam, you will be given an application form to complete. The instructor will submit this form to ODA for processing. After ODA has processed the application, then:

  • If you do not have a pesticide license, ODA will then send you an invoice for a $30 application fee. After paying the application fee, ODA will issue you a certification card that will expire in three years on March 31.
  • If you have a current pesticide license, the $30 fee is waived. ODA will issue you a new pesticide license card, with the fertilizer certification endorsed on it. This certification will expire on the same three-year cycle as your pesticide recertification credits.

Certified Crop Advisors (CCA) and Certified Livestock Managers (CLM) do not need this training or exam. They should contact our office for an application form.

  • To renew a current certificate, you will need to either:
    • Attend a 1 hour recertification class, or 
    • Pass the exam within 12 months of submitting the renewal application

If you do not have a pesticide license, ODA will mail you a renewal application in December, and an invoice for a $30 application fee.

Exam & Study Material

To get a new certificate, or to renew an existing one, you can either attend a training class or pass the certification exam. Exams are valid for 1 year; you must submit an application and fee (if applicable) within 1 year of taking the exam. If not, you will need to retake the exam or training class.

Exams are offered around the state throughout the year. Seating is limited at these exam sessions, and it is strongly recommended that you reserve a seat if you plan to take an exam. If you do not have a reservation, you will need to wait until a reserved seat becomes available. There is no cost to take exams.

Recertification

To remain certified, the applicator must prove he or she is competent every three years. They can do this by either:

  • retaking the exam, or
  • attending an approved 1 hour continuing education class.

ODA will mail information about your current credit hour status with your renewal application. You can also check your status online here:

Check Recert status

Recertification classes are offered by OSU Extension and other approved sponsors throughout the year. At these classes they will provide you with a form to complete, including your name, address, and license number. At the end of each class, you will be provided with a code number to enter on the form. One copy of the form you will keep for your records, and another copy will be submitted to us by the program sponsor. Note: some classes will charge you a registration fee to attend. This registration fee is not the license fee you may owe when you mail us your renewal application.
