Data Story
About Soil in Hall County, Texas
Alkaline sands in the Red River Valley
Hall County features fine sand with a pH of 7.51, which is notably higher than the 6.5 national median. The sandy nature of this soil makes it unique among its neighbors.
Dominant sand content limits retention
The soil is nearly 60% sand (59.5%) with only 15.3% clay. This high sand percentage makes for easy digging but causes the soil to lose water and nutrients very quickly.
Low organic matter challenges growers
With only 1.10% organic matter, the soil is well below the 1.66% state average. The soil score of 20.7 reflects these challenges, though an AWC of 0.137 in/in provides some moisture buffer.
Maximum infiltration in group A
Classified as well drained and hydrologic group A, this soil has the highest water infiltration rates. Water disappears quickly from the surface, meaning plants need frequent, light watering.
Sun-loving plants thrive in zone 7b
Okra, southern peas, and watermelons love the warm, sandy conditions found here. Mix in plenty of compost to help your garden hold onto the nutrients it needs to produce.

Soil & Planting Advisory: Hall County
Soil Verdict
Hall County is in USDA hardiness zone 7b, a moderate climate zone. where winter lows can reach 5°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
Hall County is somewhat cooler than the Texas statewide average.
