About Soil in Fulton County, Georgia
Urban soils with acidic roots
Fulton County soils show an average pH of 5.51, which is more acidic than the national median of 6.5. Despite its urban density, the soil maintains a score of 18.8, slightly outperforming the state average soil score of 17.6.
Sandy textures dominate the landscape
The soil composition is 65.8% sand, 19.3% silt, and 14.9% clay. This high sand percentage provides excellent drainage and prevents the heavy compaction often found in higher-clay regions.
Moderate water storage for plants
Organic matter is recorded at 1.32%, trailing the state average of 1.83%. However, an available water capacity of 0.120 in/in is better than the state average, helping plants stay hydrated in metro Atlanta's heat.
Planning for urban water runoff
While specific drainage classes are missing from the data, the high sand content generally suggests rapid water movement. Gardeners should watch for quick drying in raised beds during the peak of summer.
Thriving in the Zone 8a heat
In Hardiness Zone 8a, Fulton County is ideal for growing everything from camellias to summer squash. Utilize the high sand content by planting drought-tolerant varieties or using drip irrigation.
