Texture is silt loam, loam, fine sandy loam, or sandy loam. Stratification is typical. Below 40 inches, textures include loamy sand or gravelly analogues of those textures. Thin silty clay loam, clay loam, or stony layers are in some pedons. Rock fragment content ranges from 0 to 25 percent.
Reaction is neutral to strongly acid.
The bedrock substratum phase has sandstone at a depth of 60 to 80 inches. The Holly series is in the same family. The Holly soils do not have chromas more than 2 below the surface horizon. Orrville soils formed in alluvium and are on flood plain steps on flood plains. They formed in alluvium from upland areas of low-lime drift, and from areas of sandstone, siltstone, shale, and limestone.
