Dayton soil and landscape
Soil profile: Typical profile of Dayton silt loam, 0 to 2 percent slopes. The heavy textured clay layer is between 30 and 70 centimeters. (Soil Survey of Benton County, Oregon; Matthew H. Fillmore, Natural Resources Conservation Service)
Landscape: Irish Bend cutbank in an area of Dayton silt loam, 0 to 2 percent slopes. Dayton soils are on nearly level or somewhat concave, slightly depressed parts of broad valley terraces at elevations of 150 to 400 feet. They formed in silty and clayey glaciolacustrine deposits.

Typical profile
A—0 to 9 inches; silt loam
E1—9 to 12 inches; silt loam
E2—12 to 15 inches; silt loam
2Bt1—15 to 22 inches; silty clay
2Bt2—22 to 29 inches; silty clay

2BCt2—40 to 53 inches; silt loam
3C—53 to 76 inches; silt loam
USE AND VEGETATION: These soils are used for growing spring grains, grass seed, hay and pasture. Native vegetation is grasses, weeds, rosebushes and widely spaced ash trees.
DISTRIBUTION AND EXTENT: Dayton soils are found throughout the Willamette Valley in western Oregon; MLRA 2. They are extensive.
