The bottom line on why golf courses go through the process of aerified greens is that over time it keeps the greens healthier. This is the case because: Aeration loosens soil that has been compacted by golfers walking over it and machines rolling over it. This opens up growing room for the roots and increases oxygen to the roots.
What is aerification of a golf green?
(It's also called "aerification.") To aerify a golf green a piece of machinery built for the task cores the ground (punches holes and removes the dirt) in a certain pattern. (The small cores of dirt that are removed are called "plugs.")
Why do golf courses aerate the ground?
This is the case because: 1 Aeration loosens soil that has been compacted by golfers walking over it and machines rolling over it. 2 This opens up growing room for the roots and increases oxygen to the roots. 3 The roots of the turfgrass thus can grow deeper, creating a healthier putting surface.
What happens to a golf course without aerification?

And, as the GCSAA put it, without aerification, the putting greens die: "Preventative maintenance is an integral part of successful golf course management.
What is Core aeration in golf?
Core aeration compared to a normal green. Well, along with venting aeration, many courses may choose an aeration strategy that is much more aggressive once play dies down for the year. This is known as core aeration.

Is it worth playing on aerated greens?
Putting greens receive more traffic than any other playing surface. The aeration process helps relieve the compaction caused by all that traffic. It also helps create a firm, smooth putting surface by controlling thatch and promoting healthy turf roots.
How often should you aerate a golf course?
Many golf courses will aerate two or three times in a given year. However, aeration is only done when turf is healthy and actively growing, so as to promote a speedy recovery. grasses such as bermudagrass and paspalum, core aeration is best performed in late spring and throughout the summer.

Golf courses aerate their greens for four major reasons, all of which affect turf health. Aeration is usually performed in order to remove organic matter, decompress the soil, improve the drainage of the soil, and help promote root growth.
How long does aeration last?
Therefore, to achieve sustained benefits from aeration, courses must routinely aerate – i.e., aerate approximately once every six weeks or more frequently.
Can you putt on aerated greens?
The holes punched during aeration are smaller and the greens heal more quickly than the old days of course maintenance. Still, there is no denying that recently aerated greens play differently than greens in peak condition. They roll more slowly and the punched holes can knock a putt off line.
What happens if you don't aerate your lawn?

What is the difference between aeration and Aerification?
Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions.
Why do golf courses punch the greens?
The Purpose of Punching The goal of aerating greens is twofold. First, the process helps to reduce the likelihood that the soil will compact on the greens. The second goal is to get air circulating down through the soil and the roots. The hope is that this will keep everything healthy for many years to come.
Why do golf courses put sand on the greens?

How many times do golf courses aerate?
Many golf courses will aerate two or three times in a given year.
Why is golf course soil compacted?
Compacted soil, created from foot traffic, weather and other factors, reduces oxygen levels in the soil and can inhibit water getting to turf roots. All of this compacting and organic matter can also make for a softer golf course because it's unable to drain water and push new turf to the surface.
Why do you curse yourself for a golf course?

The holes left behind are filled ...
What is aeration in golf?

Why do we aerate grass?
Aeration primarily is performed to control organic matter – i.e., decaying roots and grass stems – relieve soil compaction, stimulate root growth and improve drainage. If organic matter becomes too thick, it acts like a sponge and holds water at the surface after rain or irrigation.
