2C horizon:
Hue—7.5YR or 10YR
Value—4 to 6
Chroma—2 to 6
Texture—loam or sandy loam
635A—Lismod silt loam, 0 to 2 percent
slopes
Setting
Landform: Moraines and till plains
Position on the landform: Footslopes
Slope range: 0 to 2 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
Lisbon and similar soils: 85 percent
Dissimilar soils: 15 percent
Similar soils:
• soils that have no subsurface layer
• soils that contain more sand in the upper and
middle parts of the subsoil
• soils that contain carbonates at a depth of more
than 40 inches
• soils that are overlain by recent, light-colored
deposition
Dissimilar soils:
• the poorly drained Pella soils in drainageways
• the well drained Parmod soils and the moderately
well drained Geryune and Windere soils in the higher
positions on the landform
