Hello Kerry

CSU Soil lab in Fort Collins conducts soil tests including levels of various minerals (nutrients) and pH. You can mail the sample in and they will send the results to you via email. All the forms and information you need can be found at 

https://www.soiltestinglab.colostate.edu/. When I pulled that address up I see that they are suspending testing for a couple of months. If you are testing in order to make changes to your garden next growing season you can probably delay the test until they resume in November. If you need information sooner let me know and I can try to find an alternative option for you.
