ATTENTION: The season for soil tests has come to a close. There are some situations that  call for a late Fall soil test, but in general, we are recommending only pH testing at this time. Luckily, we do that for free! Follow the same procedures as with our regular testing.

The SCD employs one full-time soil scientist who is available to answer any soil-related questions and requests for technical assistance. We offer low-cost soil tests to the public for urban landowners (lawn & garden) and small acre farms. The Lawn and Garden Test includes phosphorous, nitrogen, potassium, pH, and organic matter; the Small Farms test also includes sulfur. 

The lab fee (per single sample) is $30 for a Lawn and Garden Soil and $35 for a Small Farms Soil test, payable by cash, check and credit/debit. Print and fill out the form (below) to include with your sample and payment; the form provides soil sampling tips & techniques. Drop off your soil sample during our office hours, 8am to 4:30pm, Monday through Friday.

Soil Survey
Although the soils in Spokane County have not changed, there have been significant changes in technology, land use and a need for soil information. In 1998 the SCD partnered with the Natural Resource Conservation Service (NRCS) to update the Spokane County Soil Survey, which, until then, had remained unchanged for 30 years.

The Soil Survey is now available online at http://websoilsurvey.nrcs.usda.gov/. Using the Web Soil Survey you can access data for your area and determine suitability of the soils for a particular use. You can download or print a customized report for free.

If you have any questions about the results of either your soil test and/or the soil survey, please contact Eric Choker who can provide site-specific soil interpretations and workshops on how to utilize the soil survey for maximum results.
