Lance Gunderson Explains the HANEY Soil Health Test, Feb14 2020

Lance Gunderson explains the science behind the Haney and PLFA soil health tests, and how to interpret test results.
The Haney Soil Health Test measures the nutrient needs and overall health of your soil. Some Haney measurements are similar to traditional soil tests. Soil pH and organic matter, for example, are measured in the same way as traditional soil tests. But the Haney test uses different extracts than traditional soil tests use, to measure nutrients like N, P, K and trace. Haney’s special extracts (H2O -water, and H3A, similar to acids produced by plant roots to break down soil minerals) are meant to mimic nature, and more accurately measure the amount of nutrients that your plants can actually access.
For some nutrients like nitrate, Haney tests and traditional soil tests might have quite similar values, because their different extracts pull nitrate out of the soil at the same rate. But for other nutrients like phosphorus or trace, Haney test values will be quite different from values in traditional soil tests, because their different extracts pull phosphorus or trace out of the soil at different rates.
The Haney Test also evaluates soil health indicators such as soil respiration, the water-soluble fractions of organic carbon and organic nitrogen and the ratios between them. A soil health score is calculated based on a combination of these different soil health indicators. The Haney test then recommends a cover crop mix (% legumes: %grasses), to help you balance your C: N ratio and feed your soil microbes, to improve your soil health.
Finally, if you provide a “crop to be grown” and “yield goal” at the time of sampling, you will be provided with recommended application rates of N, P, K and trace.
We do NOT recommend that you discard your traditional soil testing and just rely on Haney test results for fertilizing. Rather, continue using both tests for several years to learn how they match up or disagree, and to figure out which tests are most useful for you.

Love your Science for the Citizens, I too have donated my life for truth and the truth set me free from my health issues. Thank you for all you do. ❤

At 3:05 he mentions "Ray Shires".
I can't find that name with regenerative practices. Am I spelling it right?

[@lancegunderson86]

I believe that is spelled correctly. Ray was a regenerative producer in North Carolina and is where Ray Archuleta (Ray the Soil Guy) was introduced to numerous different practices on the farm, that he went on to discuss as part of his teachings. I believe that Mr. Shires passed away a few years ago.
