Good horse pasture in the Charlotte region starts with a soil test, not a bag of seed. Test through the NC Department of Agriculture's free lab, correct pH with lime before you spend money on fertilizer, choose forages that fit Piedmont clay and the horses you keep, and then control grazing so the stand you built survives. Most failing pastures skipped the first step or ignored the last one.
Step 1: Get a soil test from NCDA&CS
North Carolina horse owners have a real advantage: the NC Department of Agriculture and Consumer Services (NCDA&CS) Agronomic Division runs the state soil lab, and residents pay nothing for most of the year. The division says soil tests are free from April 1 through late November. For 2026, the peak-season fee of $5 per sample starts Dec. 1. To get a free test, the sample must be physically at the lab at 4300 Reedy Creek Road in Raleigh by 5 p.m. on Nov. 30.
That deadline is about arrival, not mailing. NCDA&CS notes that county Extension offices are run by NC State, not the department, and the fee depends on when samples reach the Raleigh lab. Many county offices carry boxes to Raleigh as a courtesy, but transport schedules vary, so ask your office (Mecklenburg, Union, Iredell, Cabarrus, or wherever the farm sits) when its last run before Dec. 1 leaves.
How to sample a pasture
The lab's instructions for pastures differ from those for cropland:
"A core should be 0 to 8 inches deep for plowed fields and 0 to 4 inches deep for no-till or pastures."
- Collect 15 to 20 cores per sample and mix them in a clean plastic bucket.
- Use a stainless steel probe, shovel, or trowel. NCDA&CS warns that brass or bronze tools add copper and galvanized buckets add zinc.
- Sample each pasture separately. Don't combine areas with different soil types or fertilizer histories.
- If one area is clearly doing worse, sample it on its own. Cabarrus County Extension recommends this for poorly performing areas, and on a horse farm that often means the ground around gates and water.
- Label every box with an ID you can match to a farm map, so next year's results compare field to field.
- Wait for wet ground to drain. In the lab's words, "Soil too wet to till is too wet to sample."
Cabarrus County Extension notes that the lab is busiest in winter and early spring, so results can take longer then. Sampling in early fall beats the fee and leaves time to lime before spring growth.
Step 2: Fix pH before you buy fertilizer
When the report comes back, start with lime. Fertilizer does little on acidic soil.
"For tall fescue and orchardgrass production, a pH range of 5.7-6.5 is generally considered ideal."
N.C. Cooperative Extension, Stokes County Center: Don't Forget About Lime
The same article explains that unamended soils in the Southeast typically fall below that range, some as low as 4.0, especially red clay. It calls lime one of the most economical soil amendments, because fertilizer on low-pH soil isn't available to the plants. It also recommends fall liming, since lime then has time to work before spring growth.
If the pasture is bermudagrass, NC State Extension says it grows best at pH 5.5 or higher, with an ideal range of 5.8 to 6.0, or up to 6.5 if you overseed legumes.
Two details people miss on the report:
- The fertilizer recommendation is a yearly total. Moore County Extension points out that if you plan four applications, you divide the recommended amount by four. Applying the full number each time is an expensive mistake.
- Nitrogen and tall fescue. Penn State Extension notes that nitrogen fertilization can raise ergovaline, the toxin in endophyte-infected fescue. On a broodmare farm, discuss nitrogen rates with your Extension agent.
Step 3: Choose forages that fit the Piedmont
NC State Extension places North Carolina in the "transition zone" between northern and southern climates, an area also called the "tall fescue belt" because tall fescue is the dominant forage. In the Piedmont, tall fescue has long dominated. Cool-season grasses grow best at 65°F to 75°F and warm-season grasses at 80°F to 95°F. No single forage grows year-round here, so the goal is a combination that covers the gaps.
A practical mix for a Charlotte-area farm usually involves:
- Tall fescue for spring and fall growth. NC State notes that tall fescue keeps live leaves into winter better than most species, which makes it the standard choice for stockpiling (letting growth accumulate in fall for winter grazing).
- Bermudagrass for summer. NC State says it is best adapted to the Piedmont and coastal plain, needs good drainage, and makes minimal growth once night temperatures fall below 60°F. It also does poorly in shade, so shady paddocks need a different plan. Cool-season annuals can be no-till drilled into bermudagrass in fall to extend grazing.
- A legume such as clover. Burke County Extension notes that legumes add nitrogen and that keeping clover to 35 to 40 percent of the mix minimizes slobbering. It suggests keeping mixtures simple, with two grasses and one legume as a starting point.
Broodmares and tall fescue
Many fescue stands carry an endophyte, a fungus that makes the plant hardy but produces a toxin called ergovaline. Penn State Extension notes that if a pasture has tall fescue you didn't plant, chances are good it is Kentucky 31, an infected variety. It explains that ergovaline causes reproductive problems in late-term mares, including prolonged gestation, thickened or retained placentas, and poor milk production.
"You cannot tell visually whether a plant is infected."
Penn State Extension, Evaluating and Managing the Risk of Tall Fescue Toxicosis to Broodmares
Penn State cites University of Kentucky researchers who rate a pasture under 10 percent tall fescue as low risk, 25 to 50 percent as significant risk, and 50 to 100 percent as high risk. Labs can test for the infection rate and the ergovaline level. Penn State's main recommendation is to move mares off high-risk pasture 30 to 90 days before foaling, and to work with your veterinarian if that isn't possible. For new seedings, it notes that novel-endophyte fescue varieties are safe for broodmares, while endophyte-free fescue is less grazing tolerant.
For geldings and pleasure horses, Penn State says research is not conclusive and there are no widespread recommendations to avoid infected fescue. The broodmare question is the one that changes how you manage the pasture.
Step 4: Match horses to acres, then rotate
Burke County Extension puts the general guideline at one 1,000-pound horse per 2 acres. Penn State Extension says 2 to 4 acres per horse is needed for full-time turnout without overgrazing. Beyond that, the fix is control over when and where horses graze.
"Horses should be in a paddock for no longer than seven days, because that is how long it takes for forage regrowth to begin after grazing."
Penn State Extension, How to Make Rotational Grazing Work on Your Horse Farm
Penn State's model is at least four paddocks gated to one sacrifice lot that holds the shelter and water. Turn horses into a paddock at 6 to 8 inches of growth and move them when about half is gone, leaving 3 to 4 inches. Never graze below 3 inches. Burke County Extension gives the same 3 to 4 inch floor for tall fescue and orchardgrass, because those grasses store their reserves near the crown.
A worked example. Four horses of about 1,000 pounds each on 10 acres works out to 2.5 acres per horse, inside both guidelines. Set aside about an acre as a sacrifice lot and split the rest into four paddocks of roughly 2.25 acres. If each paddock is grazed for up to seven days, the others rest about three weeks. In hot weather, Penn State notes cool-season grass may need 6 to 8 weeks to recover, so rotate by forage height, not the calendar. A bermudagrass paddock earns its keep in July and August.
Temporary electric fencing inside a solid perimeter fence is an inexpensive way to subdivide, and mowing right after horses leave evens out regrowth.
Step 5: Give winter a place to happen
Moore County Extension says warm-season grasses go dormant starting in October and need protection from traffic. A sacrifice area can be a dry lot or your least productive paddock. The same article notes that the ground around a water trough can become dead space up to 100 feet out. Feeding hay in a different spot daily or weekly spreads that damage out and returns manure, urine, and leftover hay to the soil.
If horses will spend winter on one lot, put it where mud won't run toward a stream or well. For manure handling and runoff control, see our eco-friendly barn ideas for North Carolina horse farms.
Step 6: Treat weeds as a symptom
Penn State Extension puts it plainly: if pastures were overgrazed and you renovate without changing grazing, they will look the same again in a short time. A dense stand is the first line of weed control.
Carolina horse nettle is a good local example. Polk County Extension describes it as a spiny warm-season perennial with pale purple and yellow flowers and tomato-like fruit. It contains solanine and can be toxic in large amounts, although livestock generally won't eat enough of it when other forage is available. The keys to control are stopping seed formation and killing the root system. Frequent mowing prevents flowering. If you use herbicide, Polk County Extension reports that GrazonNext HL and Chaparral do more than 2,4-D because they damage the roots. Use only products labeled for pasture, and follow any grazing restrictions on the label.
