Where Can I Find Sample Boxes? 

In North Carolina, boxes and forms for sampling are available from any Cooperative Extension office (find your local County Center).

How Do I Submit Samples?

During the peak fee season (December 1 – March 31), completed samples should be mailed to the N.C. Department of Agriculture and Consumer Service’s soil testing lab in Raleigh, whose address can be found on the soil sample box and submission form. Download a submission form for home lawn and garden samples.

What Does It Cost?  

Samples submitted between April 1 - November 30 are analyzed free of charge. North Carolina is one of the few states to offer soil testing at no direct cost to its residents most of the year because of funding derived from a statewide commercial fertilizer. A peak season fee of $4 per sample is charged for each sample submitted between December 1 - March 31.
