About Soil in Gallia County, Ohio
High Acidity in Gallia Soil
Gallia County has a significantly acidic soil profile with an average pH of 5.26, well below the national median of 6.5. This level is also lower than the state average of 5.97, which will influence which plants can thrive without soil amendments.
Silty Texture with Low Clay
The soil is comprised of 45.5% silt and only 16.9% clay, creating a texture that is less prone to the heavy clumping found in other parts of Ohio. With 24.9% sand, the soil remains relatively loose and manageable for manual gardening.
Exceptional Organic Matter Content
Gallia boasts a massive organic matter content of 10.35%, more than double the Ohio state average. Despite this richness, the available water capacity is 0.160 in/in, suggesting that the soil does not hold moisture as well as its organic content might imply.
Managing a Low Soil Score
With a soil score of 50.4, Gallia sits below the state average of 66.0, indicating some natural limitations for intensive farming. Although specific drainage classes are not recorded, the lower water capacity suggests a need for consistent moisture management.
Zone 6b's Acid-Loving Haven
This acidic, high-organic soil is a natural fit for blueberries, azaleas, and rhododendrons in Zone 6b. Capitalize on the incredible organic matter by planting crops that enjoy rich, well-aerated environments.
