About Us

The Soil Testing Laboratory is part of the Department of Soil, Water, and Climate in the College of Food, Agricultural and Natural Resources.

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