Soil Testing

A soil test is an analysis of the soil that is used to diagnose soil type, pH, and any nutrient deficiencies that may exist. Soil testing can be done professionally by commercial soil laboratories or your local cooperative extension. Some nurseries have do-it-yourself soil-test kits available that can indicate certain specific problems but their results are limited.

Colorado State University routinely analyzes soil samples for pH, soluble salts, organic matter, nitrate nitrogen, phosphorus, potassium, zinc, iron, copper, manganese, lime and soil texture. They do not test for herbicides, insecticides or foreign chemicals.

Included in a report from the Colorado State University Soil Testing Laboratory are interpretations that relate results to fertilizer and management recommendations.

Contact us for directions on correctly collecting soil samples. You can obtain the necessary forms for submitting those samples at this site:   http://www.colostate.edu/Depts/SoilCrop/soillab.html

Samples should be mailed to:

          Soil, Water and Plant Testing Laboratory

Colorado State University

Room A 319 NESB

Fort Collins, CO 80523-1120

Do not send samples to the local cooperative extension office.
