The 2023 Agricultural Fertilizer FIRST-TIME Certification Webinar will be held on March 22, 2023 from 8:30 am – 12:30 pm. The deadline for applicators to register is March 15, 2023. The fee to register is $35



This 3-hour training is for individuals who are obtaining their Ohio Agricultural Fertilizer Applicator Certification for the first time (not recertification). Agricultural Fertilizer Certification is required for applications to more than 50 acres of crops grown for sale in Ohio. It is not required for lawn and landscape fertilizer applications. This training will be held online as a webinar. Following the completion of this course, we will collect your information to be transferred to the Ohio Department of Agriculture. If you currently hold a pesticide license, your license information will then be updated to include fertilizer certification. If you do not hold a pesticide license, you will be sent an invoice to collect your certification fee. Once the fee is received by the Ohio Department of Agriculture, you will receive your fertilizer certification.
