There is another good article in the Green Section Record, this one by Blake Meentemeyer and Brian Whitlark on Turfgrass Fertilization. You'll want to read the full article. It talks about the overall goals of fertilizer application, soil tests, some myth busting, fertilizer and playability, and more. It's a modern article with a lot of historical references too.

The most interesting part of the article for me was the economic case study. A course reduced the putting green fertilizer cost by 82% and the result was "the putting greens have never been healthier."
