About Soil in Jefferson County, Ohio
Acidic soil in Jefferson's hills
Jefferson County's soil is notably acidic with an average pH of 5.61, falling well below the national median of 6.5. While taxonomic data for the region is limited, this acidity suggests a need for soil amendments in traditional vegetable gardening. Gardeners should expect to manage pH levels to unlock essential nutrients for most crops.
A silty foundation for local growth
The soil composition is dominated by silt at 49.3%, balanced by 24.2% sand and 19.0% clay. This mix provides a smooth texture that is generally easy to work and manage. The balanced clay content helps retain nutrients while the silt ensures the soil doesn't compact as easily as pure clay would.
High organic matter despite lower storage
At 7.00%, Jefferson's organic matter far exceeds the state average of 4.85% and the national average of 2.0%. However, its available water capacity of 0.156 in/in sits below the Ohio average of 0.186 in/in. This means while the soil is naturally rich in nutrients, it holds onto moisture less effectively during dry spells.
Navigating Jefferson's water movement
Specific drainage and hydrologic classifications are unavailable for this county's primary soil profiles. However, the high silt and moderate clay percentages suggest the ground likely moves water at a steady, moderate pace. Local builders and farmers should perform site-specific tests to confirm drainage rates before major projects.
Gardening in Hardiness Zone 6b
With a 6b hardiness zone and high organic matter, this soil is ideal for acid-loving berries and hardy perennials. Blueberries and rhododendrons will thrive in the naturally low pH environment. Start a garden today by testing your specific plot to see if your vegetables need a lime boost.
