Lecture 5 b Soil Orders & Suborders in Minnesota, Soils of the week, and Wisconsin State Soil

Suborder Map Soils of Minnesota

PM = till, loess, outwash, lacustrine and bedrock. Minnesota soils are variable due to PM, Climate, Topography and Vegetation ( time is similar) PM = till, loess, outwash, lacustrine and bedrock. Climate = drier from east to west Topography = slope position Vegetation = Prairie and Forest

Soil Change due to Human Influence

Clarion – Udoll a prairie soil on Des Moines Lobe Till, on summits and hill slopes, well drained.

Zimmerman – Psamment – a forested soil on outwash on hillslopes and summits, well drained.

Nashwauk - Udalf – a forested soil on Des Moines Lobe till on summits and hill slopes, well drained.

Fargo – Aquert – a prairie soil on lacustrine deposits, low areas, poorly drained, dry climate. Bgss

Webster – Aquoll – a prairie soil on Des Moines Lobe till, in low areas. Poorly Drained.

Barnes – Udoll – a dry prairie soil on Des Moines Lobe Till on hill slopes and summits, well drained.

Port Byron - Udoll – a prairie soil from loess on hill slopes and summits well drained.

Ahmeek- Udept – a forested soil on Superior Lobe Till, on hill slopes and summits, well drained. DYSTRIC EUTRUDEPTS

Wisconsin Soils

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 http://www.wi.nrcs.usda.gov/technical/soil/antigo.html
