Agricultural Fertilizer Applicator Certification

Senate Bill 150 provides the state with tools to continue to serve a growing population while protecting Ohio's natural resources. Focusing on science-based practices, the bill requires farmers with 50 or more acres to attend a course on fertilizer application. This certification process supports responsible agricultural practices and promotes the 4R program while allowing Ohio to continue to grow its vital agriculture industry.
