Soil testing and plant analysis aid commercial growers, gardeners, and homeowners in making decisions about fertilizing or applying soil amendments. This fertilizer guide lists a variety of laboratories serving Oregon, and provides specific information about laboratory services.

To compile this list, the OSU Extension Service requested information from labs providing services for Oregon and adjacent areas. OSU Extension Service makes no endorsement by listing a laboratory; conversely, omission of a laboratory does not indicate that it's unsuitable. Another source for locating commercial laboratories is the yellow pages of your local telephone directory.

Before submitting material to a lab, pay attention to the following guidelines:

  • Be sure the test you request is the right one to answer your question. Nutrients aren't the only factor for successful crop production, so a soil test may not tell you why your plants don't grow. Ask a county agent or other agriculture professional which tests you may need.
  • The goal of a soil or tissue test is a fertilizer recommendation. Fertilizer recommendations are based on soil/tissue tests that follow a set procedure or recipe. For example, OSU fertilizer recommendations are based on procedures used in OSU's Central Analytical Laboratory. Many labs say they use "comparable" procedures, but they may not. A laboratory that uses a procedure different from OSU's most likely will give a different fertilizer recommendation.
  • Before sending samples, call the lab to inquire about costs and shipping instructions. For example, soil samples to be tested for nitrate-nitrogen should be refrigerated or dried rather than sent moist at room temperature.
  • Beware of low prices. Laboratory procedures cost money to perform. A lab quoting a low price usually analyzes a few elements and estimates the others. You do not want estimates--make sure you obtain results from analytical work.
  • For information on taking soil samples, see EC 628, Soil Sampling for Home Gardens and Small Acreages.
