Soil, Water and Plant Testing Laboratory at Colorado State University

A soil test is the best way to check the growing potential of your garden.
You can buy the most attractive plants in the greenhouse or order the best seeds, but they won’t produce the best results if the soil lacks the proper nutrition or the proper qualities the soil should have.
A soil test will take the guess work out of your garden’s growing potential. It will guide you in deciding which nutrients are lacking and sometimes, more importantly, which you have too much of. Overfertilizing is a common gardening problem. It is not only expensive, but it may harm your garden’s production and our environment.
CSU Extension helps enables you to have your garden soil tested to check on
your garden’s progress.

Please note, that you mail your soil samples up to the lab in Fort Collins (until it moves down here to Denver with the opening of the Spur Campus!) and that we do not accept soil samples at the Denver Extension office. Once you receive your results, we would be happy to review them with you!

To learn more and get your soil tested visit the Soil, Water and Plant Testing Laboratory at Colorado State University.
