Dr. Chas Schmid has been involved with many of the same topics I often study and consider---sand topdressing, potassium fertilization, soil organic matter, putting green performance, and so on. His data, and plenty of photographic evidence, also show that there can be completely different outcomes than what I might have expected. We discuss this, on a range of topics, in this episode.
