Superior Water Storage Potential
At 1.56%, organic matter levels trail the state average of 4.15% significantly. Despite this, the soil holds water exceptionally well with an available water capacity of 0.167 in/in, surpassing the state's typical benchmark.
Moisture-Retentive Regional Landscape
Official drainage and hydrologic classifications are currently unavailable for this specific region. However, the high silt and clay concentration suggests a landscape that retains moisture longer than its sandier neighbors.

Soil & Planting Advisory: Woodruff County
Soil Verdict
Woodruff 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
Woodruff County closely matches the Arkansas average hardiness conditions.
