Data Story
About Soil in Tyrrell County, North Carolina
Highly Acidic Coastal Lowlands
Tyrrell County features highly acidic soil with an average pH of 4.66, significantly lower than the national median of 6.5. This measurement even falls below the North Carolina state average of 5.14, indicating a specialized environment for native flora. While taxonomic data is limited here, the acidity suggests a high presence of organic acids common in coastal plains.
A Sandy and Silty Blend
The soil composition consists of 40.5% sand and 30.0% silt, creating a mix that offers moderate workability. With only 10.6% clay, these soils generally lack the heavy compaction found in the Piedmont. This balance allows for decent aeration while the high silt content provides a smooth texture for root expansion.
Exceptional Organic Matter Levels
Tyrrell County boasts a remarkable 16.51% organic matter, dwarfing the national average of 2.0% and the state average of 5.12%. This rich carbon content drives an impressive Available Water Capacity of 0.209 in/in. Such high fertility creates a soil score of 62.9, more than double the North Carolina average of 29.4.
Hydrology in the Coastal Plain
Specific drainage and hydrologic group data are currently unavailable for this county profile. However, the high water capacity suggests the soil holds moisture effectively, which is vital for the region's agricultural stability. Local growers should monitor site-specific saturation levels given the high organic content and coastal elevation.
Thriving in Hardiness Zone 8b
Located in USDA Hardiness Zone 8b, Tyrrell County is ideal for blueberries and other acid-loving crops that thrive in high organic matter. The long growing season and nutrient-dense soil provide a unique advantage for coastal gardening. Start your garden today by selecting plants that love rich, moist, and acidic conditions.

Soil & Planting Advisory: Tyrrell County
Soil Verdict
Tyrrell County is in USDA hardiness zone 8b, a warm climate zone. where winter lows can reach 15°F. Mild winters mean soil rarely freezes deeply, allowing year-round microbial activity and faster organic matter breakdown.
Planting Guidance
Warm-season crops, citrus relatives, and heat-loving ornamentals do well. Cool-season vegetables should be planted in fall and winter. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.
Soil Implications
Warm soils accelerate organic matter breakdown, so compost and mulch need replenishing more frequently than in cooler zones. Sandy soils common in warm zones drain quickly; water-retentive amendments like compost or peat help hold moisture.
Regional Context
Tyrrell County closely matches the North Carolina average hardiness conditions.
