Producers rely on soil testing laboratories to provide nutrient recommendations for crops. Producers can submit samples to the Auburn University Soil, Forage and Water Testing Laboratory for analysis.  Both routine analysis, as well as more advanced testing, are available from the Lab.

Routine Analysis

For routine soil analysis, samples are analyzed for pH, phosphorus, potassium, magnesium, and calcium.  A soil test report detailing soil test values, ratings and, lime and fertilizer recommendations is sent to the customer by e-mail and/or regular mail within 24 hours after the samples are received by the lab.

Special Soil Analysis

In addition to the routine analysis, soil samples are extracted by different methods and analyzed for calcium (Ca), magnesium (Mg), potassium (K), copper (Cu), iron (Fe), manganese (Mn), zinc (Zn), barium (B), cadmium (Cd), chromium (Cr), lead (Pb), sodium (Na), nickel (Ni) and others by ICP (inductively coupled plasma). Also, total nitrogen (N), carbon (C), sulfur (S), organic matter, nitrate (NO3-N), ammonium (NH4-N), particle size, soluble salts, alkalinity, electrical conductivity, saturated media extract for potting media, pecan package analysis and many others. These analyses will take more time to complete depending on the type of analysis requested and number of samples. Limited interpretations of the results will be provided upon requested.
