It’s a perfect, sunny morning and you’ve just reached the first green in regulation. You feel great and you know you’re within birdie range. Then, you see them, those little holes in the green. Arrggh! They’ve just aerified the course, and it’s going to ruin your round, right? Well, maybe not. Consider the fact that PGA Tour legend Tom Watson shot a sizzling record 58 at his then-home course, Kansas City Country Club, just days after the greens had been aerified. Consider also that aerification is merely a short-term disruption that has long-term benefits for golf courses. When you see them, remember that without those little holes, the greens would eventually die.
Preventative maintenance is an integral part of successful golf course management. Golfers view aerification as an inconvenience that takes the greens out of play for a day, pulling cores from the greens and leaving holes that can affect putting for many days before healing. To add insult to injury, aerification is best done in many part of the country during mid-summer, at the height of the playing season and when most greens are in prime condition. But a golfer needs to understand how important aerification is to producing healthy turf. Aerification (also known as aeration) achieves three important objectives. It relieves soil compaction, it provides a method to improve the soil mixture around the highest part of a green’s roots and it reduces or prevents the accumulation of excess thatch. Like so many things, the quality of a good putting green is more than skin deep. In fact, the condition of a green has a lot to do with what goes on below the surface. In order for grass to grow at 3/16-inch, it must have deep, healthy roots. Good roots demand oxygen. In good soil, they get the oxygen from tiny pockets of air trapped between soil and sand particles. Over time, the traffic from golfers’s feet (as well as mowing equipment) tends to compact the soil under the putting green – particularly when the soil contains a lot of clay. When soil becomes compacted, the air pockets on which the roots depend are crushed, and the roots are essentially left gasping for air. Without oxygen, the grass plants become weaker and will eventually wither and die.
So to sum things up, it is a necessary evil that must take place to ensure quality playing conditions throughout the year. The maintenance staff works very hard year round to make sure we have excellent playing conditions and we need to give them the respect they deserve. The next time you see someone on the maintenance staff please take a moment and give them a compliment. It will go much further than you think.
Keep it in the fairway!
