Practical experiences using USGA method for measuring surface organic material in golf greens

Abstract Experience from using loss on ignition with verdure intact on more than 1000 greens in Scandinavia tells us there is no magic number for the percentage of organic material in golf greens. Only with a clear purpose, a sampling compliant with the purpose, observations during sample preparations, and a team effort for evaluating the results can you make decisions on how and what to improve maintenance methods to gain business benefits from better playing quality.
