About Soil in Lewis County, Kentucky

Typical Kentucky Acidity

Lewis County soils feature a pH of 5.79, nearly identical to the Kentucky state average of 5.80. This acidic profile falls well below the national median of 6.5, suggesting a frequent need for soil amendments like lime.

Silt-Driven Soil Mix

The soil mix is silt-heavy at 56.5%, balanced by 24.1% sand and 19.3% clay. This high silt content provides excellent workability but requires careful management to prevent surface crusting and compaction.

Standard Nutrient Capacity

Organic matter levels reach 2.46%, which beats the national average of 2.0% but lags behind the Kentucky average of 3.55%. The available water capacity stands at 0.181 inches, offering standard hydration support for local crops.

Moisture Management Needed

Specific drainage class data is currently unavailable, though the high silt percentage typically indicates moderate permeability. Builders and farmers should perform site-specific tests to ensure stable foundations and healthy roots.

Soil & Planting Advisory: Lewis County

Soil Verdict

Lewis County is in USDA hardiness zone 6b, a moderate climate zone. where winter lows can reach -5°F. Freeze-thaw cycles are moderate; soil biology slows in winter but recovers reliably in spring, supporting a broad range of plants.

Planting Guidance

A wide plant palette is possible: deciduous trees, most shrubs, cool-season vegetables, and many perennials thrive here. Winter protection (mulch, burlap wraps) helps push the zone boundary for desired species. 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

Moderate freeze-thaw cycles naturally aerate the soil but can also cause compaction in clay-heavy areas; annual core aeration is beneficial. Organic matter amendments decompose at a moderate pace — aim for 3-5% organic content for optimal fertility. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.

Regional Context

Lewis County is somewhat cooler than the Kentucky statewide average.
