Data Story
About Soil in Pierce County, Georgia
Acidic Ultisols Define the Pierce Landscape
Pierce County is characterized by sandy loam soils belonging to the Ultisols taxonomic order. With an average pH of 5.04, the ground is significantly more acidic than the national median of 6.5 and slightly below the state average of 5.26.
A Gritty Mix Dominated by Sand
The soil profile consists of 81.1% sand, 12.6% silt, and only 6.4% clay. This high sand content ensures excellent workability but indicates the soil may struggle to retain essential nutrients for long periods.
Strong Organic Matter but Low Water Storage
Organic matter reaches a healthy 2.33%, which beats the Georgia average of 1.83% and the national 2.0% benchmark. However, the available water capacity is low at 0.076 in/in, meaning plants require consistent irrigation during dry spells.
Well-Drained Soils with Selective Infiltration
Most of the county features well-drained soil, though it falls into hydrologic group C. This combination suggests that while surface drainage is good, the subsoil may restrict water movement more than pure sand would.
Heat-Loving Crops Thrive in Zone 9a
In USDA hardiness zone 9a, Pierce County offers a long, warm growing season. Blueberries and pecans are excellent choices for this acidic, sandy environment, provided you manage the low water retention.
