Soil Test Kits- Self Service

Typically we have FREE soil test kits at Colorado State University Extension Office at 17 N. Spruce Street, however, we are currently waiting on a shipment from the State Lab. We have other options! If you go to: you will be able to find the instructions for a soil test kit. On the last page there are instructions on using a sealed, zipper type bag, to send in your samples. Please contact us if you have questions.

There is a self service station set up at the reception desk on the first floor of the building. We only ask that you please complete a client contact sheet for our records.

Each Kit includes:
  • a collection container
  • A form with instructions and prices
Please fill out the top portion of the yellow client contact sheet and leave in the purple folder at the front desk.
Take the kit home and collect soil then send it to our Fort Collins campus where a lab analyzes the soil. The cost of the soil test varies upon on type of analysis selected on the request form and is paid to the lab in Ft. Collins.
You may take as many kits as you’d like; however, each separate area costs $35 (for the basic test), so we ask that you please take only the kits that you plan to send in. (Examples of separate areas would be vegetable garden, lawn, flower bed).
