A typical soil series description with range in
characteristics is included, in alphabetical order, in this
section. Additional information specific to this map
unit, such as horizon depth and textures, is available
in the “Soil Properties” section in Part II of this
publication.
Composition
Caprell and similar soils: 85 percent
Dissimilar soils: 15 percent
Similar soils:
• soils that are moderately eroded
• soils that have a darker and thicker surface layer
• soils that have a seasonal high water table at a
depth of less than 6 feet
• soils that contain carbonates at a depth of less than
20 inches or more than 48 inches
• soils that contain less sand and more silt in the
middle part of the subsoil
Dissimilar soils:
• the somewhat poorly drained Lismod and Torox
soils in the lower positions on the landform
• the poorly drained Pella soils in drainageways
