Thanks for your question to Ask an Expert about soil testing. You may find some basic test kits that measure pH levels at your local garden center. But to find out the levels of other nutrients in your soil you will want to have a lab do a more complete analysis. In Washington County you can contact the following lab:

10220 SW Nimbus Ave. Bldg. K-9
Portland, OR 97223
Phone: (503) 968-9225

They will provide information on the type and cost of analyses and how to collect samples for testing.
