624D2—Caprell silt loam, 6 to 12 percent
slopes, eroded
Setting
Landform: Moraines and till plains
Position on the landform: Backslopes
Slope range: 6 to 12 percent
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 contain carbonates at a depth of less than
20 inches or more than 48 inches
• soils that are severely eroded
• soils that have slopes of less than 6 percent or
more than 12 percent
Dissimilar soils:
• the somewhat poorly drained Lismod and Torox
soils in the lower positions on the landform
• the poorly drained Pella soils in drainageways

Composition
Caprell and similar soils: 85 percent

• soils that are moderately eroded
• soils that have slopes of less than 12 percent or
more than 20 percent
• soils that contain carbonates at a depth of less than
20 inches
Dissimilar soils:
• calcareous soils in positions on the landform similar
to those of the Caprell soil
• the somewhat poorly drained Lismod and Torox
soils in the lower positions on the landform
• the poorly drained Pella soils in drainageways
