The Lake County Extension office suggests Penn State Agricultural Analytical Services Lab for all your soil testing needs.
Commercial and homeowner forms can be found below:
Individual Analysis Form - optional analysis only - not for standard soil test
Turnaround time for routine soil analysis is approximately 3-7 days from the time samples are received.
Be sure to see the sampling instructions before collecting, drying, and mailing your sample. The one cup soil sample can be mailed in a zip type sandwich bag that is then placed into a small padded envelope or small box. Don't forget to include the form and a check for $9.00 per sample when mailing to Penn State's lab.
If you have any questions before you take your sample or after your results are received from the lab, contact Tom deHaas at firstname.lastname@example.org.
