Here's how we did it. After getting the small cardboard sample containers from the Forsyth County Extension Service, we dug up cores of soil from the various fields and poured them in boxes for each specific area. Once the forms for each box were completed (indicating what will be grown in the soil) we mailed all the samples (eight in all) to NC State in Raleigh.
NC is unusual in offering this as a free service for NC gardeners and farmers.
Our report will come back via Internet and in writing. It will tell whether we need to add lime, other fertilizers, what the pH is, and what the organic content is. Before we add anything to our soil, this test will guide us.. If you are thinking of doing this for your own garden, now is a good time to do it before everyone starts sending in their samples. The results will come more quickly.
