The Franklin County Extension office now has soil testing kits available for sale.

Testing is available for gardens, home lawns, farm fields, and commercial horticulture operations. Each sample is analyzed for water pH, Mehlich buffer lime requirement, and for phosphorus, potassium, magnesium, and calcium by the Mehlich 3 (ICP) test. The final report includes the chemical analysis of the soil along with lime and fertilizer recommendations for the crop specified. For agronomic crops, Mehlich 3 zinc, copper and sulfur are also reported. Analysis is done at a non-biased university soil testing laboratory at Penn State University.

Instructions and a soil testing fact sheet are included.



Kits are $13 each plus shipping. (Kits may be purchased in office. Accepted forms of payment credit card, check, or cash.)
