Soil labs by state
Wyoming
In Wyoming, University of Wyoming Extension is the main public-facing resource for homeowners, gardeners, and small-acreage residents, with county offices across all 23 counties plus the Wind River Indian Reservation. On the current UW soil-sampling pages, UW provides sampling instructions and points residents to analytical labs such as Colorado State University’s Soil, Water and Plant Testing Laboratory rather than showing a current UW homeowner soil-testing lab submission page.

- Before sampling, separate obviously different areas—such as lawn, garden, and problem spots—into different samples so results are useful.
- Use the lab’s current submission form and label each bag clearly to match the sample ID on the paperwork.
