Ohio's New Agriculture Fertilizer Certification Requirements

Click here for a brochure summarizing certification requirements: 

What fertilizer is included in the certification?:  Fertilizer is any substance containing nitrogen, phosphorus, potassium, or other plant nutrient in a dry or liquid formulation. All application types (broadcast, side dress, sub-surface, knifing, etc.) are included in the certification requirement. The only application exempted is start-up fertilizers that are applied through a planter and manure.  For this certification requirement, lime and limestone are not considered fertilizers.



ODA Releases two new Nutrient Management Tools

The Ohio Applicator Forecast:  an online tool used to help identify times when nutrient loss from a fertilizer or manure application will be minimal.  By taking data from the National Weather Service, this tool can predict the potential for runoff to occur in an area.  For more information, visit agri.ohio.gov/divs/plant/OhioApplicatorForecast/oaf.aspx

The Ohio Agricultural Stewardship Verification Program: This pilot program is a certification for farmers who protect farmland and natural resources by implementing best managment practices.  Farmers in targeted watersheds in Henry and Wood Counties who apply and meet criteria developed by the ODA's Division of Soil and Water Conservation can be certified.  Please visit your local Soil and Water Conservation District Office for more information.
