Soil Testing Overview
We utilize a variety of testing methodologies to measure the abundance of life in soils and soil amendments. All testing methods are scientifically validated. Results provide indicators of soil health and function (references available upon request).
Testing packages and the individual assays are defined below. Except where noted, these tests do not identify specific organisms. Biology tests measure the Biomass of Total Populations in general categories of the functional groups. (Some below assays identify to species). Totals of these groups represent a snapshot of the biological profile or nutrient profile of the soil or amendment at the time of testing. While some of these tests can be performed singularly, together they represent a comprehensive picture of the health and utility of the material tested.
