About Soil in Accomack County, Virginia
Less Acidic Coastal Soils
Accomack's soil shows an average pH of 5.65, which is more acidic than the national median of 6.5. However, it is significantly less acidic than the Virginia state average of 5.23, making it stand out in the region. While specific taxonomic data is unavailable, the high soil score of 39.9 reflects a profile that outperforms most Virginia counties.
Sandy Shores and Easy Working
With a high sand content of 70.1% and only 8.0% clay, this soil offers exceptional workability for local farmers. The 17.8% silt provides some structure, but the dominant sand ensures the soil remains loose and crumbly. This mix allows for easy root penetration but requires careful moisture management.
Rich Organic Matter Boosts Growth
The county boasts an organic matter content of 4.60%, which is nearly double the national average of 2.0% and far exceeds the state's 2.90%. Despite this fertility, the available water capacity sits at 0.100 in/in, falling below the state average of 0.143. This means the soil holds nutrients well but dries out faster than neighboring regions.
Rapid Drainage in Coastal Plains
While specific drainage and hydrologic classifications are not formally listed, the 70.1% sand composition indicates a highly permeable profile. Rainwater likely moves through this soil quickly, which prevents pooling but may lead to leaching of nutrients. Builders and gardeners should plan for fast-draining conditions across the county.
Warm Coastal Gardening in Zone 8a
Accomack sits in Hardiness Zone 8a, allowing for a longer growing season than most of Virginia. The sandy, high-organic soil is perfect for sweet potatoes, asparagus, and salt-tolerant coastal shrubs. Residents can take advantage of these warm conditions to start early spring gardens.
