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

plants. Also feel free to use this document, Soil Testing: A Guide for Farms with Diverse
Vegetable Crops. Another helpful resource is this document on carbon-nitrogen ratios.
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.
