Wisconsin State Soil - Antigo Silt Loam (Typic glossoboralf) - Created during the last great glaciers, Antigo Silt Loam was designated the official state soil in 1983 by Wisconsin Act 33 to remind Wisconsinites of their soil stewardship responsibilities. Advocates argued that soil, a natural resource that took 10,000 years to produce, is essential to Wisconsin’s economy and is also the foundation of life. Selected to represent the more than 500 major soil types in Wisconsin, Antigo Silt Loam is a productive, level, silty soil of glacial origin, subsequently enriched by organic matter from prehistoric forests. The soil, named after a Wisconsin city, is found chiefly in Wisconsin and stretches in patches across the north centralpart of the state. It is a versatile soil that supports dairying, potato growing, and timber. The addition of the s tate soil was the result of a successful drive led by Professor Francis D. Hole, a UW-Madison soil scientist.
