No links = Thresholds that still need to be determined, using the Waypoint Lab A-17 soil test plus an A-19-2 organic matter test that are run from the top 2 inches of soil taken from next to seedlings of each species, and the tests run, data only, in a bar graph format.

A second soil sample is taken from bare soil within 10 feet of the first sample, to confirm the threshold levels set by the first soil sample. Each soil sample needs to be a one-quart ziplock bag full, which has been sifted through a inch mesh screen to remove any rocks or vegetation matter.  Details and the sample form to send in with the soil samples to the Waypoint Lab, can be downloaded at http://www.ecoseeds.com/Waypoint-Lab-testing.pdf
