Soil Fertility Testing Program 

This program is designed as a soil-management tool for farmers, homeowners, landscape contractors, golf-course superintendents, ornamental nurserymen and others interested in the fertility of their soil and in determining the optimum lime and fertilizer requirements of their crop. 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. Standard soil test kits may be purchased from county offices of the Penn State Cooperative Extension or from commercial firms or garden centers that stock kits for the convenience of their customers.  Alternatively, you can print soil submission forms (pdf format) from this site  and submit your soil sample(s), with payment, to the laboratory in your own sample container.   Multiple sample information forms and kits are also available for individuals submitting three or more samples.  The multiple sample forms allow for up to 6 samples per page, therefore, reducing paperwork.
