Each fall season, we do a good bit of soil testing. Samples are taken from several fairways, several tees and a couple of our putting greens. The samples from tees and fairways are sent to Harris Labs/AgSource in Nebraska while the greens testing is done in Pittsburgh, PA by Dr. David York. I’ve used Dr. York for many years and trust his soil testing methods on sand based root zones. The results of these tests determine what kind of fertility program is required for the following year. Private labs have a faster turn around than most university soil labs.
