Who needs a fertilizer certification? Fertilizer certification is required if you apply fertilizer (other than manure) to more than 50 acres used for 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.

Certification training focuses on nutrient stewardship:

  • Protect water quality
  • Improve fertilizer efficiency
  • Reduce liability and risk
  • Stay informed on best practices

There are three training options in Holmes County. Please call 330-674-3015 to pre-register.
