Wisconsin Soils Program

Soil Survey work in Wisconsin began in the early 1900s shortly after the inception of the National Cooperative Soil Survey.  On May 14, 2006, over 100 years of Wisconsin  soil survey work was completed when the digital soils data for Iron County, Wisconsin was posted to the Soil Data Mart bringing digital soils coverage for Wisconsin to 100%.  This accomplishment could not have been achieved without the National Cooperative Soil Survey program, which in Wisconsin is a joint effort of the NRCS and other federal, state, and local agencies.  Principal state cooperators include the University of Wisconsin-Madison & Stevens Point, and the Wisconsin Geological and Natural History Survey.

MLRAs in Wisconsin

Soil Survey by MLRA
In 1995, NRCS reorganized the National Cooperative Soil Survey (NCSS) mapping program to a Major Land Resource Area (MLRA) basis in order to develop a seamless, higher quality digital soil survey of the U.S.

Bluff Prairie Ecological Site Descriptions Now Available

Recently, NRCS staff in Wisconsin and Minnesota completed the first two Ecological Site Descriptions (ESDs) for Wisconsin. These two ESDs represent the iconic “bluff prairie” ecosystems of Driftless region.  These sites occur throughout the region, but become prominent along the south- and west-facing bluffs of the Mississippi and Wisconsin Rivers, and their tributaries. Often they are overgrown with eastern redcedar and other woody plants. Removal of these trees and shrubs along with introduction of prescribed fire often results in an impressive restoration of these important prairie ecosystems. These ESDs provide a synthesis and framework for the inventory, description, and restoration of these plant communities
