Data Story
About Soil in Sevier County, Arkansas
Acidic Soil Profiles Near the State Average
Sevier County records an average pH of 5.48, which is nearly identical to the Arkansas state average of 5.56. This level is significantly more acidic than the national 6.5 median, requiring lime for many traditional garden crops.
High Silt Content for Better Nutrient Retention
The soil composition includes 37.3% sand and 40.7% silt, providing a stable foundation for root systems. Clay makes up 19.8% of the mix, which helps the soil hold onto nutrients more effectively than sandier neighboring counties.
Strong Water Capacity Boosts Growing Potential
With an available water capacity of 0.171 in/in, this soil stores significantly more moisture than the state average of 0.148 in/in. Organic matter sits at 3.01%, providing a solid foundation for plant health despite being lower than the statewide figure.
Slow Drainage Challenges Traditional Building
The soil belongs to hydrologic group D, which indicates very slow infiltration rates when the ground is saturated. This high runoff potential requires careful site planning for both farming and home construction.
Thriving Pine and Produce in Zone 8a
Hardiness zone 8a supports a wide range of fruit and timber, with Sevier's water retention specifically benefiting thirsty summer vegetables. Local gardeners should test their soil frequently to manage the naturally low pH levels.

Soil & Planting Advisory: Sevier County
Soil Verdict
Sevier County is in USDA hardiness zone 8a, a warm climate zone. where winter lows can reach 10°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
Sevier County closely matches the Arkansas average hardiness conditions.
