About Soil in Hardeman County, Tennessee
Acidic Soils with High Silt Content
Hardeman County records an average pH of 5.27, which is just slightly below the state average of 5.35. This acidic environment is characteristic of West Tennessee's weathered soil profiles.
Silty Soils Dominate the Texture
Silt makes up a significant 57.6% of the soil, paired with 18.9% clay and 23.5% sand. This high silt ratio can lead to a smooth, floury feel but may become easily compacted under heavy machinery.
High Water Capacity Despite Low Organic Matter
The organic matter is low at 1.27%, yet the available water capacity is impressive at 0.188 in/in. This exceeds the state average of 0.171, meaning the soil holds moisture well even if it lacks high natural nutrients.
Undefined Drainage Class Needs Observation
Specific drainage and hydrologic group data are not currently available for the county's dominant soil types. Landowners should monitor runoff patterns after heavy rains to determine the best locations for drainage-sensitive projects.
Thriving in the 7b Hardiness Zone
