Soil samples are analyzed for specific soil nutrients to determine proper application rates of fertilizer and lime for optimum plant growth. Routine analysis includes soil pH, P, K, Ca, Mg, Zn, Mn, Cu, Fe, and B. Soluble Salts and Organic Matter tests are also available. Completed soil test results, along with a recommendation on fertilization and liming, are mailed to the client.  Sampling and mailing instructions are found on the sample boxes and forms, which should be sent directly to the lab with the soil sample and payment. Soil sample boxes and information sheets are available at your local Extension office.
