COVID-19 Update

The Soil Testing Lab is open for business.  But due to COVID-19 safety measures, we cannot accept in-person sample hand-off.  Please mail or ship your samples to us, or plan to use our drop-box if you're on campus during business hours. Please also understand that there may be slight delays in some laboratory functions.  All samples will be analyzed as quickly as possible.  Should we be forced to temporarily suspend operations, samples will be properly stored for future testing.  Please email us at soiltest@umn.edu, or call 612-625-3101 for more information.  (Hours are 8:00-4:30 Monday through Friday, but office coverage is currently spotty, so email messages may result in the fastest response.)
