About Soil in Lake County, Tennessee
Elite Mollisols of the Mississippi
Lake County boasts a remarkable soil score of 64.5, by far the highest in this group. Its pH of 6.57 is nearly neutral, matching the national median and far exceeding the Tennessee state average of 5.35.
Rich silty clay deposits
The soil is a heavy silty clay, containing 50.6% silt and 27.9% clay. This high clay content allows the soil to hold onto massive amounts of nutrients, making it some of the most productive land in the state.
Superior water and organic levels
The soil features an impressive available water capacity of 0.184 in/in, well above the state average. While the 2.20% organic matter is slightly below the state average, it is higher than the national average and supports intense crop growth.
Managing heavy, wet soils
These soils are somewhat poorly drained and fall into the C/D hydrologic group. Because they are so heavy and hold so much water, they can be prone to saturation and may require careful management to prevent compaction.
Agricultural powerhouse in Zone 7b
This is prime land for cotton, soybeans, and high-yield vegetable farming. The naturally neutral pH means most garden crops will thrive here with very little adjustment—just start planting!

Hydrologic Group
Group C — Moderate-High Runoff
Soils with slow infiltration rates, often with a layer that impedes downward water movement. Higher clay content restricts drainage.
Drainage Class
Somewhat poorly drained
Water is removed slowly enough that the soil is wet at shallow depths for significant periods. Mottling present.
