Data Story
About Soil in Richmond County, Virginia
Coastal Plain Acidic Base
Richmond County records a very acidic average pH of 4.95, which is much lower than the national median of 6.5. This measurement is also lower than the Virginia state average of 5.23. The soil requires careful management for pH-sensitive crops common to the Northern Neck area.
Coarse Texture and Light Silt
The soil composition is 58.0% sand, 27.9% silt, and 11.1% clay. This high-sand mix provides a loose, workable texture that allows roots to penetrate easily. The low clay content keeps the soil from becoming compacted, though it offers less natural mineral fertility than heavier soils.
Healthy Organic Matter Levels
The organic matter content is 2.92%, which beats the national average and slightly exceeds the state average of 2.90%. Despite the high organic matter, the available water capacity is 0.135 in/in, trailing the state average of 0.143 in/in. This suggests that while the soil is fertile, it may dry out faster than average during summer months.
Rapid Water Movement Potential
Specific drainage and hydrologic data are unavailable, but the 58% sand content typically indicates well-drained conditions. This is beneficial for preventing root rot in many crops but requires attentive irrigation during dry spells. Builders should note the low clay content when assessing site stability.
Success in Zone 7b
The 7b hardiness zone supports a wide range of vegetables, small fruits, and ornamentals. High organic matter levels make this soil excellent for intensive gardening if pH is adjusted. Start a compost pile today to maintain these healthy organic levels and improve water retention.
