About Soil in Madison County, Ohio
A Mucky Base with Histosols Heritage
Madison County's soil consists of Histosols with a distinctive muck texture and an average pH of 6.27. While slightly more acidic than the national median of 6.5, it remains significantly less acidic than the state average of 5.97. These characteristics indicate a soil rich in organic material and history.
High Silt Levels Support Soil Structure
The soil composition features 51.7% silt and 21.1% clay, mixed with 22.7% sand. This balance provides a stable structure that retains nutrients well but can feel heavy when wet. Workability depends on timing, as the high silt content makes the soil susceptible to surface crusting.
Elite Fertility Outperforms the State
With an organic matter content of 6.49%, Madison County far exceeds the Ohio average of 4.85%. The available water capacity reaches 0.212 in/in, which is significantly higher than the state benchmark of 0.186. This combination creates an exceptional environment for intensive crop production.
Navigating Very Poor Drainage Challenges
The dominant drainage class is 'very poorly drained' with an A/D hydrologic group designation. This means the soil requires careful water management, such as tiling or raised beds, to be productive for farming or building. Without proper intervention, the soil holds water for long periods.
Abundant Growth in Zone 6a
Located in USDA Hardiness Zone 6a, this county is a powerhouse for corn, soybeans, and moisture-tolerant vegetables. Gardeners should embrace the high organic matter to grow lush greens and heavy-feeding perennials. Start your garden today to take advantage of some of Ohio's highest-quality soil.
