Welcome to the Soil, Water and Plant Testing Laboratory at Colorado State University!


We will stop receiving soil, water, and plant samples starting Sept. 20. We expect that we will restart regular operations in mid-November. If you sent samples and they are expected to arrive next week, we will communicate with you about testing options. Customer service, accounting, and other communications will continue as normal.

If you have questions or concerns, please send us an email to

Hints for Homeowners:

The Soil, Water and Plant Testing Lab offers gift certificates for soil tests!

Trying to figure out what to give the gardener, farmer or rancher in your life? The Soil, Water and Plant Testing Lab offers gift certificates for soil testing at only $35.00 per sample.

The test includes an analysis of pH, soil salts and nutrient levels in the soil as well as an interpretation of the results. Soil testing is a great way to evaluate salts, nutrient availability and the effects of adding composts or other amendments to the soil.

Gift certificates are always available and can be used at any time. Call the lab at 970-491-5061 or email for more information

The Availability of Parking for the Soil, Water, and Plant Testing LabThe three, 30 minute temporary parking spaces that were once available in front of the Natural and Environmental Sciences Building (NESB) have been eliminated and converted to a bus stop. This has been a problem for some of our clients who drop off samples for the lab. Alternative parking is available in the loading zones at the south end of the NESB and at the southwest corner of Libby Coy Way. and University Ave, just east of the Shepardson Building.  The loading zone areas allow for a time period of 20 minutes. There are also two 30 minute parking spots on Mason St., just east of the General Services Building and a pay lot at the corner of Pitkin St and Libby Coy Way just west of the motor pool. Unfortunately, the pay lot requires payment for a minimum of 1 hour.
