John Peters, Director, UW Soil Testing Laboratories

SGS Mowers Soil Testing Plus of Toulon, IL has withdrawn from the Wisconsin certification program.  Therefore, as of March 2012, there are now six laboratories certified by the Wisconsin Department of Agriculture, Trade and Consumer Protection for soil testing in Wisconsin.  To become certified, laboratories must meet certain analytical performance standards and are also required to;

  • Use analytical procedures outlined in the most recent edition of Wisconsin Soil Testing and Plant Analysis Procedures, Department of Soil Science, UW-Madison.
  • Provide soil test recommendations for lime and nutrients as prescribed in the most recent edition of Soil Test Recommendations for Field, Vegetable, and Fruit Crops (A2809), Department of Soil Science, UW-Madison.

The names and contact information for the certified laboratories are listed below.
