About Us

The Soil Testing Laboratory is an analytical service laboratory providing Universities, state and federal agencies, private companies, and the general public with quality environmental analyses. With over 100 tests available, our goals are to provide a high level of analytical precision, quality, and accuracy, with timely results, to every client, for every sample tested. 

Soil testing takes the guesswork out of fertilizer recommendations, ensuring fertile soil without pollution of the environment, and makes good economic sense. Our recommendations are based on laboratory measurements, soil characteristics, crop history, and crop nutrient requirements and are specific to Minnesota and the surrounding region. 

The Soil Testing Laboratory is part of the Minnesota Agricultural Experiment Station's Soil Testing and Research Analytical Laboratory (STRAL). STRAL partners with Department of Soil, Water, and Climate in the College of Food, Agricultural and Natural Resources and University of Minnesota Extension to provide soil testing services.
