Whenever I read about a supt. who doesn't hollow core aerify I cringe, not because I disagree with their agronomic methods, but because I know that someone somewhere will grab on to that info and think it means they don't have to hollow core either. One thing to remember when it comes to golf course management, every process is interdependent upon every other process. The fact that Steve doesn't need to hollow core is just one snap shot of his total management plan. To be in the same boat as him would mean greens construction, water quality and use, fertility, weather, grass type and many other factors were similar to what he's is doing and dealing with. Whenever someone wishes to adopt similar management practices as another course it's tough to just take bits and pieces. So, I caution anyone here in a position of power at their golf club to study all the factors that determine why they, and anyone else, aerifies the way they do before they consider any changes to their agronomic management plan
