About Soil in Buchanan County, Virginia

Moderately acidic mountain soils

Buchanan County's soil pH stands at 5.34, which is the highest in this group and above the state average of 5.23. It remains lower than the national median of 6.5, suggesting a moderately acidic environment. This profile supports the diverse hardwood forests common in the Appalachian Plateau.

Light and silty textures

The soil contains 43.1% sand and 31.9% silt, with a very low clay content of 11.5%. This lack of clay makes the soil exceptionally light and prevents the 'heavy' feel found in other parts of the state. It is a highly workable soil that resists the clumping and crusting common in clay-heavy regions.

Extraordinary organic matter content

Buchanan leads the region with a massive 11.38% organic matter, nearly four times the state average of 2.90%. Surprisingly, its available water capacity is slightly lower than average at 0.134 in/in. This suggests a soil that is incredibly rich in nutrients but may drain faster than its dark color implies.
