About Soil in Clark County, Kentucky

Balanced Soil in the Bluegrass

Clark County presents a soil profile with an average pH of 6.16, making it more neutral than the Kentucky state average of 5.80. While it sits slightly below the national median of 6.5, this acidity level is ideal for many regional forage crops. The overall soil score of 64.4 indicates high quality compared to the state average of 56.2.

Silt-Heavy Soils Drive Consistency

The county's soil consists of 53.6% silt and 27.8% clay, creating a heavy but productive texture. With only 18.6% sand, these soils hold onto nutrients well but require careful management to prevent compaction. This mix offers a stable foundation for the county's diverse agricultural landscape.

Strong Water Retention for Growth

With an Available Water Capacity of 0.189 in/in, Clark County exceeds the state average for moisture storage. The organic matter content sits at 2.75%, which is higher than the national average of 2.0% but lower than the state mark of 3.55%. This combination provides a reliable reservoir for crops during drier summer months.

Managed Hydrology and Drainage

Specific drainage class and hydrologic group data are currently limited for this area. However, the high silt and clay content suggests that water moves slowly through the profile. Farmers and builders should account for this natural retention when planning irrigation or site drainage.

Thriving in Hardiness Zone 6b

Located in USDA Hardiness Zone 6b, Clark County is perfect for cool-season grasses, berries, and native hardwoods. The balanced pH and high water capacity make it an excellent spot for a home vegetable garden. Start your planting in early spring to take full advantage of these fertile Bluegrass soils.
