Golf is a sport and is played on grass. The greenkeeper works with the grass to produce the best possible playing surface for golf. But just as each golf course has its own design and setting into the landscape, so also the grass on each golf course is growing in its own soil, in a particular climate, with an innumerable list of differences from any other golf course. By understanding and then applying scientific principles of greenkeeping, the results are predictable, and the playing surface can be optimized at any golf course. That’s what this book is about.
