Data Story
About Soil in Lynn County, Texas
High alkalinity on the High Plains
The soil in Lynn County is notably alkaline, with an average pH of 7.86. This is significantly higher than the national median of 6.5 and requires selecting plants that are tolerant of lime-rich conditions.
Sandy soils dominate
A high sand content of 55.0% makes this soil very porous and easy to till. With 21.0% clay and 23.8% silt, it lacks the heavy density of eastern Texas soils, allowing for deep root penetration.
Near-average moisture retention
Available water capacity is 0.132 in/in, virtually identical to the Texas state average. Organic matter levels are 1.46%, suggesting that adding compost could help boost the soil's natural productivity.
Slow water movement
Despite the sandy texture, this soil is classified in hydrologic group D, indicating slow infiltration and high runoff risk. Managing the surface to prevent crusting will help ensure water reaches the roots during rain events.
Thriving in hardiness zone 8a
Hardiness zone 8a is ideal for sorghum and heat-tolerant vegetables like okra. With such workable sandy soil, your garden will be easy to plant and maintain all season long!

Soil & Planting Advisory: Lynn County
Soil Verdict
Lynn 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
Lynn County closely matches the Texas average hardiness conditions. The zone range of 7b-8a within the county means soil and planting decisions should account for local elevation and topography.
