Ohio Soil Regions

The Ohio Department of Natural Resources generalized the soils in the state into twelve soils regions (See Figure 2). Most of the watershed is within Region four, referred to as Miamian-Kokomo-Eldean. Only a small part of the watershed lies within the third Region, Blount-Pewamo-Glynwood. These names are given to the soil regions because they represent common soil series in the described region. Both Regions 3 and 4 are entirely within the Indiana and Ohio Till Plain. Soils north of Big Darby Creek in Union County are in Region 3 which have higher clay, lime, and organic content than soils to the south in Region 4 which are coarser in texture and contain more well-drained soils. Figure 3 summarizes the differences between soil regions in Ohio .
