NC Soil Test Fee: Free Through Nov. 30, $5 From December

A soil test that costs nothing in November costs $5 a sample starting Dec. 1, up from $4 in the winter of 2025-26. The North Carolina Department of Agriculture and Consumer Services (NCDA&CS) says its soil testing is free from April 1 through Nov. 30, 2026 and $5 per sample beginning Dec. 1. Wayne County’s Cooperative Extension office has urged gardeners to submit samples before Thanksgiving, and the state’s deadline leaves only a few extra days after the holiday.

The Fee Moves From Free to $5 on Dec. 1

The Goldsboro Daily News, in a Nov. 1 gardening column citing the N.C. Cooperative Extension Wayne County Center, said samples submitted from April through November are generally processed without a fee and that gardeners are encouraged to submit before Thanksgiving to use the free period. The column listed the seasonal fee as $4 per sample.

That figure is out of date. NCDA&CS announced in February that the lab would raise some testing fees beginning March 2, and its release says the peak-season rate will increase from $4 to $5 per sample. Agriculture Commissioner Steve Troxler said the higher fees will be invested back into laboratory operations, upgrading older equipment with newer technology. The department’s current soil-testing page and its peak soil season page both list $5.

The peak season runs from Dec. 1 through March 31, 2027, according to an NCDA&CS September news release. County Extension pages and newspaper columns written before the change, including a Sampson County Extension post from 2025, still carry the $4 figure.

Why Arrival Date, Not Mailing Date, Sets the Price

The deadline is tighter than Thanksgiving suggests. The September release says samples must physically arrive at the lab by 5 p.m. Monday, Nov. 30, to avoid the fee. The department’s peak soil season page says the fee depends only on when samples reach the lab at 4300 Reedy Creek Road in Raleigh. Postmarks, online submission dates and drop-offs at county Extension offices do not count.

The same page says USPS does not deliver to the lab’s physical location, so mail sent that way does not help. Deliveries by hand or by UPS or FedEx are accepted Monday through Friday from 6 a.m. to 5 p.m., excluding state holidays, and the page advises arriving by 4 p.m. when help is needed because security gates close at 5 p.m. Thanksgiving Day, Nov. 26, is a state holiday.

The free period applies to North Carolina residents, according to the release. Troxler said the peak-season fee has helped spread the sample processing time out, which benefits farmers and residents.

Taking a Soil Sample From a Lawn or Garden Bed

The Sampson County Extension post describes the basics. A good sample is made of several subsamples collected from the area and mixed together so the result represents the whole bed or lawn. Galvanized tools should be avoided because samples can be contaminated by micronutrients when collected with them, the post says. The soil is best mixed in a clean plastic bucket.

A fall test also pairs with other seasonal work. A post on this site about a Clemson fall soil test and lime explains why an early result gives lime months to work before spring planting.

The department’s September release lists the packaging steps for sending the sample in:

Use an official NCDA&CS soil sample box, filled to the red line.
Complete the soil submission form, including a crop code, email address and phone number, or use the PALS online portal and enclose a printed copy of the form.
Make sure the form matches the information on the box, and keep a copy.
Pack the boxes in a sturdy container, not a padded envelope.

Boxes and forms are available at county Cooperative Extension offices or at the Agronomic Services Division in Raleigh, the release says. The Wayne County Center is at 3114 Wayne Memorial Drive in Goldsboro, according to the Goldsboro Daily News column.

What Soil Tests Do and Do Not Cover

The Agronomic Services page says soilless media, such as potting mixes with less than 50 percent native soil, should not go to the soil lab and instead belong in the department’s soilless media analysis program. The division does not test soil for contaminants.

The Sampson County post says results usually take about two weeks, and that results are sent by email if an address is provided on the submission form. The post also notes that clients and advisors must log into the PALS portal to retrieve reports, unless an email address was given.

The Wayne County column folded the soil-test reminder into a longer list of November chores. It put the average first fall freeze at the Cherry Research Station near Goldsboro around Nov. 6, though that varies, and advised moving tropical container plants indoors and covering hardy plants with frost cloth kept off the foliage. For trees and shrubs, it said November is a good planting month, with the root flare left unburied and mulch kept several inches from the trunk. Warm-season lawns such as Bermuda, centipede, St. Augustine and zoysia should skip nitrogen once they go dormant, according to the column.

A soil test fits in the same window. Results that come back before spring tell a gardener whether a bed needs lime or fertilizer, and a sample sent in November avoids the new fee entirely.

For gardeners planning spring beds or a lime application, the practical steps are short: collect the sample now, use an official box, ship it with a carrier that delivers to the lab’s street address, and confirm that it arrives before 5 p.m. on Nov. 30.
