The Extension office recommends and offers soil testing. Soil testing is free for Boone County residents. Soil testing is $5 per sample for non-Boone County residents (residents of other Kentucky counties can get soil tests in their home county for free). Check or cash in exact change required. We recommend submitting samples as early as possible. Our soil lab is undergoing remodel, and processing time has been longer than the normal 2-3 weeks.
