Wisconsin Certified Soil Testing Laboratories –
November 2006

John Peters, Director
UW Soil Testing Laboratories

Logan Labs of Russell Point, OH has withdrawn from the Wisconsin certification program. Therefore, as of November 2006, there are now seven 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, in addition, are 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 fertilizer as prescribed in the most recent edition of Soil Test Recommendations for Field, Vegetable, and Fruit Crops (A2809), Department of Soil Science, UW-Madison. This publication is currently being updated with the revisions scheduled to take effect on Jan. 1, 2007.

The names and contact information for the certified laboratories are listed below. If you have any questions about this program, please contact Sue Porter at WDATCP (608-224-4605) or John Peters (715-387-2523).
