Data Story
About Soil in Flagler County, Florida
Acidic Sands Define the Flagler Landscape
Flagler County features an average soil pH of 5.08, which is slightly less acidic than the Florida average of 4.88. However, this level remains significantly more acidic than the national median of 6.5, requiring specific plant choices. Local data on taxonomic order remains limited, but the chemical profile suggests a typical coastal Florida chemistry.
A Heavily Sandy Composition Affects Drainage
The soil is overwhelmingly sand at 83.3%, with minimal silt and clay at 3.0% and 4.1% respectively. This high sand content ensures easy workability but offers very little natural nutrient retention. Gardeners here must manage a substrate that moves water and minerals through the profile rapidly.
Rich Organic Matter Boosts Growing Potential
With 8.28% organic matter, Flagler outperforms both the state average of 8.03% and the national average of 2.0%. The available water capacity sits at 0.109 in/in, providing a stable foundation for plant health. This combination helps offset the nutrient leaching common in sandy soils.
Managing Water Flow in Coastal Soils
While specific drainage and hydrologic classifications are not formally listed for this area, the 83.3% sand content suggests high permeability. Building and farming projects must account for rapid infiltration rather than surface runoff. These characteristics generally favor structures that require well-draining foundations.
Thriving in Hardiness Zone 9b
Flagler County sits in USDA Hardiness Zone 9b, making it ideal for citrus, blueberries, and salt-tolerant ornamentals. The high organic matter provides a head start for backyard vegetable gardens if you monitor the acidic pH. Start your garden today with acid-loving varieties like azaleas or camellias.
