Can the extension service for Multnomah county test soil ph #923742

Asked January 18, 2026, 11:13 AM EST

Hello I have a couple soil samples and I am needing to get the ph tested on them. Is this something the Master Gardener Extension service can help with? I'm taking a class through OSU and this is part of the assignment. Thanks for any assistance. I'm located in NE Portland. Meghan

Thank you for your question, Meghan.  Unfortunately, none of the Metro Extension offices offer soil testing.  Even the offices that do test only for pH, not soil nutrients.  The closest labs are the OSU Soil lab (https://cropandsoil.oregonstate.edu/shl/testing-services/soil-testing) and the A & L Agricultural Lab (https://al-labs-west.com/soil-analysis/).  Sorry—and good luck with your studies!
