Deadline for Fertilizer Applicator Certification Quickly Approaching

In June, 2014, Governor Kasich signed the agricultural fertilizer applicator certification law (Senate Bill 150), requiring farmers who fertilizer to 50 acres or more to become certified by September 30, 2017. Anyone wishing to become certified must fill out an application form, pay an application fee, and attend a three hour training session. At this time, there is no exam. After September 2017, the process for obtaining a license may change, and it is possible that an exam will be part of the process in the future. Training sessions hosted by OSU Extension will be posted at

Under the certification law, fertilizer is considered to be any substance containing nitrogen, phosphorus, potassium, or other plant nutrient in a dry or liquid formulation. Lime and limestone are not considered fertilizers. All application types (broadcast, side dress, sub-surface, knifing, etc.) are included in the certification requirement. The only application exempted is start-up fertilizers applied through a planter. All certifications will be valid for three years. After the deadline, the Ohio Department of Agriculture (ODA) will conduct random record audits.
