About Soil in Logan County, Kentucky
Rich but Acidic Soil
Logan County features a soil pH of 5.67, which is more acidic than both the state average of 5.80 and the national median of 6.5. This low pH level reflects the region's mineral history and often requires lime to optimize nutrient availability.
Silt-Heavy Composition
Silt dominates the landscape at 60.9%, while clay makes up 21.9% and sand fills the remaining 17.2%. This composition creates a dense, fine-textured soil that holds onto water and minerals effectively for farming.
Strong Hydration Capacity
The county’s available water capacity of 0.196 inches per inch exceeds the Kentucky average of 0.186. Organic matter sits at 2.22%, which is healthy by national standards but leaves room for improvement compared to the state's 3.55% average.
Monitoring Soil Saturation
Specific drainage and hydrologic group data are currently unavailable for this area. Growers should monitor for moisture retention, as the high silt and clay content can lead to slow drainage during heavy spring rains.
Thriving in Zone 7a
