Soil Testing Information

Due to the COVID-19 pandemic, our county MSU Extension office has reduced its in-person office hours.

Community members interested in purchasing a soil sample kit can order one online. Community members interested in dropping off soil samples for testing can mail their samples in a resealable zipper storage bag directly to the lab. Mail the sample, along with a completed informational sheet and payment, to:

MSU Soil & Plant Nutrient Laboratory
Plant and Soil Sciences Building
1066 Bogue Street, Room A81
East Lansing, Michigan 48824-1325

Checks should be made out to MSU for the correct payment according to the fee schedule. For more information, visit the MSU Soil and Plant Nutrient Laboratory website.

Clarksville Research Center
