Soil testing is the only accurate way to know if you should add lime or nutrients to your lawn or garden.
Extension Master Gardener℠ volunteers with N.C. Cooperative Extension -Chatham County Center encourage Chatham County residents and gardeners to have their soil tested 2-3 months before installing new plantings, and every 2-3 years for established lawns and gardens. Learn about the benefits of soil testing.
Between April 1st and November 25th, county residents can drop off completed soil samples to the Chatham County Center, located on the western (left) side of the Chatham County Agriculture and Conference Center, 1192 US 64 W Business, Pittsboro. Find us on Google Maps.
Retrieve boxes and forms from the drawers in the red toolbox. Place completed soil samples in the container on top of the toolbox.
Samples will be delivered to the soil test lab operated by the NC Department of Agriculture – Agronomic Services Division, in Raleigh, at no charge, as follows:
- Samples will be delivered at the end of each month, typically on or near the last Friday of the month (see schedule below)
- Samples dropped off earlier in the month will be held for end-of-the-month delivery.
- The last delivery in a year will be made on November 26th, so please drop off samples by Nov 25th.
- Samples dropped off on or after Nov. 25th will be held for April delivery.
There is no charge for soil testing most of the year. Between April 1 and Thanksgiving, NCDA Agronomic Services processes soil samples at no charge for NC residents. During the peak season, Nov 27 – March 31, there is a $4 per sample fee. We do NOT deliver samples during the peak season.
Individuals can expect to receive their results by email, typically two to three weeks after samples are delivered. Results are also posted online on the Agronomic Services Division’s PALS website.
To collect and submit samples, you will need:
- A box for each unique area you plan to sample. For example, one box for your vegetable garden, another for your lawn. Problem areas should also be sampled separately and get their own box.
- A Homeowner Soil Submission Form. You may enter up to six samples (boxes) on one sheet.
- Better yet, submit your form online (Instruction Guide for Submitting Online).
- If you submit online, you must still print a confirmation for the sample to be processed.
- Do you have a farm, managed forest, or pasture? Use the Commercial Soil Sample Form instead
- Review this soil sampling guide for accurate results.
These supplies are available from everyN.C. Cooperative Extension County Center, but most NCCE County Centers do not offer free delivery by Extension Master Gardeenr Volunteers. Find your local center.

Tips for collecting good samples:

- Sample each unique area separately
- Collect 10-12 random samples from each unique area and blend them together to fill one box
- Take samples 4” deep for lawns, 4-6” for gardens
- If soil is wet, allow it to dry before putting in boxes — do not put a plastic bag inside the soil sample box
- Fill boxes to the red fill line
- Do not tape boxes shut

- Enter up to six samples (boxes) on one form
