Why Should We Test Our Soil?

The UMN 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.

We'll take a deeper look into and provide more information about soil sampling, cover why you should consider, how to collect, how to submit, and how to interpret a soil sample submission.

Soil Test bags are available for your use and soil test probes can be checked out for your use in Sibley and Nicollet County Extension offices.
