How to Interpret Haney Soil Test Results

The Haney test is intended to select robust soil biological activity even if the overall percent organic matter isn’t great. But it’s an open question of what “enough” biological activity is, so interpreting tests like the Haney can be difficult.

How Can We Evaluate Soil Biological Properties for a Better Understanding of Soil Health? - Lance Gunderson - NNTC 2016 Presentation - MP3 Download


Soil is teaming with life. Billions of bacteria and miles of fungal filaments act as micronutrient stores and miniature highway transport systems that help a soil function to support a healthy plant community. Measuring a soil’s biological system, however, is complex and very different from the more traditional soil testing methods aimed at a soil’s fertility. Tests such as Solvita, Haney, and PLFA help producers evaluate their soil’s biological system and we are now beginning to understand and appreciate what this means for the health and function of our soils. Lance Gunderson, the executive director of soil health and new test development at Ward Laboratories in Kearney, Neb., will introduce these tests, their components and how to interpret the results, along with discussing how on-farm management may influence the soil’s biology and overall health.
