Soil, Water & Hay Testing

Testing soil, hay, and water can provide valuable information for managing your property, livestock, crops, or garden. Park County Extension can help you get started by providing sampling equipment and educational resources.
Park County Extension does not collect, process, or mail samples. After collecting your sample, you will select a testing laboratory and submit the sample directly to that lab.
