Which state agency requires the records for fertilizer applicator activities?

• A. Ohio State University Extension
• B. Environmental Protection Agency
• C. Ohio Department of Agriculture
• D. Department of Natural Resources

Answer: (C)

In Ohio, the agency that sets and enforces fertilizer rules, including requiring records of fertilizer applicator activities, is the Ohio Department of Agriculture. This department oversees the fertilizer program, licenses applicators, and requires keeping records of fertilizer purchases and applications to help protect water quality and ensure proper nutrient management. The other organizations play different roles: Ohio State University Extension provides education and guidance, not regulation; the Environmental Protection Agency is a federal body, while the Department of Natural Resources focuses on natural resources and conservation, not fertilizer recordkeeping.
