State Soil of Wisconsin - Antigo
Antigo silt loam was named the official state
soil of Wisconsin by an act of the State
Legislature in 1983, a declaration intended to
remind us of the vital importance of our soil
resources. Antigo silt loam was selected to
represent the more than 550 different soils in
Wisconsin. It is a productive, well-drained
soil with a light-colored surface layer developed
under northern hardwood forests.

• Antigo soils are formed in silty material
  underlain by sand and gravel on glacial outwash
  plains.Antigo silt loam is a versatile soil,
  supporting mainly dairy, potato, and timber
  production
