CSU Soil Testing

Note: the CSU Soil, Water and Plant Testing Lab has temporarily suspended testing. They expect to restart regular operations in mid-November. See website for more information.

The CSU Soil, Water and Plant Testing Lab in Fort Collins offers year-round soil testing. It’s a great way to check the quality of soil in your yard and learn to improve it. To use the service, gardeners must:

  • Complete the lab submission form
  • Collect a composite soil sample from the test area (detailed instructions are on the form)
  • Mail the form and soil sample to the CSU Soil, Water & Plant Testing Lab, Campus Delivery 1120 A-320 NESB, Fort Collins CO 80523-1120

The cost of a routine garden and landscape soil test through the CSU lab is $35, and the turnaround time is currently about a month. Soil test containers and instructions are available just outside the CSU Extension office in the Broomfield Library, but residents must mail samples to the lab in Fort Collins for analysis. Visit the CSU Soil Testing Lab website for more information.
