I know no subject more disparate around the country than water management, especially of golf putting greens. In the desert southwest every drop is accounted for when water can consume up to $1 million annually. While in northern states water is applied gratuitously measured in minutes (not inches) with little regard for cost or precision.
Recently the use of moisture meters such as Spectrums Field Scout 300, provide an easy to use method for determining soil moisture and a defacto increase in precision. With the simple poke of the meter into the ground golf course superintendents now have a number. The meter actually provides percent soil moisture measurements that will vary for every soil or sand rootzone. Hence the question, whats your number?, i.e., what is the level of soil moisture you feel will get you the best turf without stress, or if you start the day at 14 percent can you make it without chasing wilt?
There is an old saying in education that what gets measured gets done. It seems odd that both numbers we manage putting greens for come from the end of a metal stick! Nevertheless, developing a number for your greens will add precision to the single most important management factor during the stressful seasons, water management.
There are few regular management decisions made on a putting surface that influence performance as much as water. Hot is okay, hot and wet is the kiss of death. If you are not paying for water now, the writing is on the wall for Great Lake States and much of the northeast. The new water withdrawal legislation is a harbinger of things to come. It is best to become more precise now. At some point just like golfers ask about stimpmeter readings, when they start getting the water bill they will start asking, hey-whats your number?
