Adrian, it is wonderful that you have such a background and are able to offer so much to your clients, and to the club of which you are a member. However, it is also true that very few clubs have such expertise amongst their memberships, and in fact require dedicated volunteers to 'serve' and to help steer the direction and the priorities of the club, the course, the golf calendar, etc.
I am just finishing my second year as Green Chairman at my club in the United States. I have absolutely no formal training in agronomy, but have been reading about the subject passionately for over a decade...I'm typing this in my TV room, and the coffee table is littered with golf books, including with The Confidential Guide, The Evangelist of Golf, World Atlas of Golf, Discovering Donald Ross, etc (my wife is very tolerant). In my library are dozens of books on the subject, including everything from Doak, Klein, Dye, etc. - I have read each of these more than once, and constantly refer to them when interested in a subject (tree management, for example). I have lurked / participated in this forum for years, and have attended sessions such as Pat Mucci's event last year at Mountain Ridge, with Brad Klein, Ron Prichard, etc. In short, while I still know precious little about pesticides, growth regulators, etc., I believe I have established a strong set of priorities, and I believe I can benefit my club by 'pitching in'.
My club has an outstanding superintendent, who has been in place for over 20 years - I am in awe of his knowledge of the subject, and have been stunned to learn how much goes into the job from an agronomic perspective...like most, I had absolutely no idea how much was involved! Having said that, it is also clear that he needs strong guidance on what the clubs priorities are, and that is provided by the Green Chair - we have moved aggressively in prioritizing 'tree management' and 'firm and fast conditions', among other things - this clarity of mission has come from the Green Committee, and is being executed by the Superintendent, to everyone's immense satisfaction.
