Ohio: Soil labs by state

In Ohio, homeowner soil testing is usually handled through Ohio State University Extension guidance plus county-specific kit programs or outside labs, rather than a single statewide public routine soil lab. Ohio State’s own CFAES Agricultural and Environmental Testing Core is a research-oriented lab and says it is not equipped to process individual samples from the general public.
