“The Haney Soil Health Test offers a more comprehensive look at the nutrient needs and overall health of your soil system. However, it is not a complete evaluation of your soil’s health due to its lack in the
direct measuring of some of the other soil health indicators such as bulk density, water infiltration
rates or water holding capacity. Some of the items measured by the Haney Soil Health Test are similar
to traditional tests. Soil pH and organic matter, for example, are evaluated in the same way as the
more traditional soil tests many of you have used in the past. In addition, plant available nutrients such
as NPK are evaluated with the same instrumentation. The Haney Test, however, uses different soil
extracts, namely H3A and H2O, to determine what quantity of these nutrients are available to the crop
and accessible to the microbes. […] The Haney Test differs from traditional soil tests in that it also evaluates some soil health indicators such as soil respiration, the water-soluble fractions of organic carbon and organic nitrogen and the ratio between them. Finally, a soil health score is calculated based on a combination of these different soil health indicators.”
