About Soil in Walton County, Georgia
Acidic Ultisols Define the Landscape
Ultisols dominate the Walton County landscape with an average pH of 5.33. This acidic profile is slightly above the state average of 5.26 but falls well below the national median of 6.5.
Sandy Loam Texture and Workability
The soil features a sandy loam texture comprised of 56.3% sand, 23.0% silt, and 19.2% clay. This mix provides a balance of workability, though its high sand content requires careful nutrient management.
High Water Capacity, Lower Organic Matter
Organic matter sits at 1.42%, which is lower than the Georgia average of 1.83%. However, the available water capacity of 0.128 in/in exceeds the state benchmark of 0.114, showing good moisture retention.
Poor Drainage and Runoff Risks
Classified as poorly drained with a hydrologic group D, these soils often struggle with saturation. Farmers and builders must account for slow permeability when planning drainage systems or foundation work.
Long Growing Seasons in Zone 8a
Hardiness Zone 8a provides a long growing season for Walton County residents. Peaches and pecans thrive in this environment if soil acidity is managed through regular lime applications.
