Digging Deeper: A Comparison Between Standard Soil Tests and the Haney Soil Health Test
The Illinois Sustainable Ag Partnership (ISAP) has released our comparison guide showing the similarities and differences between a standard soil fertility test and the Haney Soil Health Test.
Based the increasing interest among agronomists and farmers alike, ISAP created this resource to dive into some of the finer points of the Haney test and try to help clarify how this test compares to the standard soil fertility test that farmers have been familiar with for decades.
This resource is designed to help agriculturists gain some additional insight into some of the concepts of soil management that often go undiscussed or simply ignored in traditional production systems in Illinois.

The Illinois Sustainable Ag Partnership’s recent publication, “An Introduction to Soil Health Practices,” clearly communicates the role of soil health practices in addressing agronomic challenges and resource concerns. Co-author Torey Colburn, Conservation Agronomist with American Farmland Trust, and Helen VanBeck, Program Manager with American Farmland Trust provide an overview of the practical agronomic information included in the guidebook, including how practices like cover crops and no-till, when managed correctly, can build soil health in the field, suppress weed pressure, and limit nutrient loss. Torey and Helen are also joined by two farmers whose stories are shared in the guidebook as real-world examples of how farmers are finding success with these practices.

The Comprehensive Assessment of Soil Health, commonly known as the Cornell Soil Health Test (CASH), is designed for farmers, gardeners, agricultural service providers, landscape managers and researchers who want to go beyond simply testing the nutrient levels of their soils. The Cornell lab was the first to offer a commercial soil health test that provides standardized information on important soil biological and physical constraints in addition to standard nutrient analyses.
Find details of the CASH assessment’s indicators and management strategies for improving soil health in the Comprehensive Assessment of Soil Health Training Manual, available free online. The lab also offers fact sheets about our lab’s specific tests and procedures.
