About Soil in Dare County, North Carolina
Extreme acidity on the Outer Banks
Dare County soil is quite acidic with a pH of 5.11, roughly standard for North Carolina but well below the 6.5 national median. The unique coastal environment dictates the soil's chemical personality.
Dominant sands and minimal clay
This is a very sandy profile at 77.6% sand, featuring the lowest clay content in the group at just 4.0%. This mix ensures water disappears rapidly from the surface, preventing puddling but increasing the risk of drought stress.
A powerhouse of organic matter
Organic matter is incredible here at 14.61%, nearly triple the North Carolina average of 5.12%. This high carbon content provides excellent natural nutrition despite the sandy texture.
High permeability for coastal living
While official drainage classes are unlisted, the 77.6% sand content suggests very high permeability. This helps manage heavy rainfall from coastal storms, though it makes retaining soil moisture for gardens a challenge.
Warmest winters in Zone 9a
As one of the few Zone 9a areas in the state, Dare County supports citrus and other tender perennials. Take advantage of your 41.7 soil score and the mild winters to start a unique coastal garden.
