About Soil in Monroe County, Ohio

Acidic Ultisols Define the Landscape

Monroe County is home to Ultisols with a silt loam texture and a pH of 5.44. This soil is more acidic than both the state average of 5.97 and the national median of 6.5. Ultisols are highly weathered soils, often found in older geological landscapes like those in southeastern Ohio.

High Silt Content Offers Soft Texture

With a high silt percentage of 57.5% and 20.6% clay, this soil feels very smooth and retains moisture well. The sand content is relatively low at 19.2%. This creates a dense soil profile that can be prone to erosion on the county's famous rolling hills.

Above Average Water Storage Capacity

The available water capacity of 0.193 in/in is higher than the state average of 0.186. Organic matter stands at 4.09%, which is slightly lower than the state average of 4.85%. Despite lower organic levels, the soil's ability to hold water makes it resilient during the warmer summer months.

Well-Drained Land with Good Infiltration

Classified as well-drained and belonging to hydrologic group B, this soil handles rainfall effectively. Group B soils have moderate infiltration rates, making them excellent for construction and diverse agricultural uses. You can expect fewer drainage issues here than in many other parts of Ohio.

Warm Zone 6b Growth Potential

The slightly warmer 6b hardiness zone allows for a fantastic variety of perennials and extended-season crops. Acid-loving plants like blueberries will find a natural home in this soil's low pH environment. Embrace the unique geology of Monroe County and start your garden this season.
