One of the most common practices for golfers is to compare the process of aerification at their course with that of their best friend, or better yet their course that they play in a different part of the country. It was common to hear from a member what the course in Florida would do, interesting as it was, it was apples and oranges. Soils are very different across numerous types of delineation boundaries.

I managed a course that glaciation had carved out a great lake, Lake Michigan. The old Lake Michigan shoreline cut right across the property. Nine holes was beautiful sandy loam soil and the other 18 was a terrible grey clay. Our aerification philosophy was different for different holes on the same property!
The photo below is of an Aerification tine known as a hollow tine. The hollow tine has a cut out which allows the soil to enter up and through the tine and eject onto the surface of whatever is being aerifyed. The above photo is a result of aerifying with a hollow tine. The core is the soil and turf that is ejected out of the tine and deposited on the soil. When hollow tine core aerification is done, the cores need to be cleaned up, either disposed of, or chopped up and incorporated into the playing surface.
The type of soil will dictate how much work and what type of process will follow core aerification.
Solid tines come in a variety of configurations. The type of solid tine that is used is chosen for whatever the goal is. A cross tine may be used for venting if the goal is to maximize surface area of soil that is to be exposed to air and if playability allows. Solid tines come in a variety of sizes and the size that is used will be chosen to balance playability with the goals.

The health of a turfgrass plant begins in the soil, it is the part of the system that the avid golfer do not see. It is easy to dismiss aerification as an unnecessary disruption, however it is critical to the success of providing a quality playing surface that can withstand the stresses that are thrown at these systems. The harder and more frequent the stress that we inflict on these systems, the more frequent and intense our cultural practices need to be.
So, don't worry, soon the playing surfaces will be healed, and the disruption will pay dividends.
