Why do golf courses aerate their Greens?

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. Without aeration, organic matter (i.e. bacteria and other plants) build up on the surface of the turf.

What happens to the Greens after the golf course is watered?

The greens are left alone for a few days (although golfers may still play them) and the grass allowed to grow. The topdressing gradually disappears as watering takes place.

Is aeration on a golf course disruptive?

Aeration can be disruptive, but the long-term benefits of aeration far outweigh the short-lived disruption. The next time you play on greens that were recently aerated, keep in mind that aeration is performed for the long-term health of the course.

What happens if your ball lands on an aerated Green?

However, on an aerated green, if your ball lands on the side of a dirt core that has been removed it can travel in a completely different direction from the predicted ball flight. So how do we make the best of aerated greens?

What is the purpose of Verticutting greens?

“Regular verticutting stimulates branching and tightens the turf.” Most superintendents will topdress greens and water heavily following verticutting. One of the benefits of verticutting, unlike aeration, is that the process has little impact on the playing surface, which is crucial to maintain to keep customers happy.

What does Aerification do to greens?

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. The roots of the turfgrass thus can grow deeper, creating a healthier putting surface.

How long does it take for golf greens to heal after aeration?

two weeksIt usually takes a golf course two weeks to recovery from properly done golf course aeration. Once the grass grows back through the aeration holes to a healthy level, the mowers and rollers come back, typically with greens as good as new.

What does aeration do for golf 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.

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.

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.

How long does aeration last on golf course?

It can take up to a couple of weeks for the greens to recover, but these procedures are critical for the long-term health of the greens. This is typically done one to three times a year, depending on the course, the type of greens, and in what part of the country they are located.

Why do they put sand on golf greens?

Sand helps cushion leaf tips and crowns and reduces algae. Increased Firmness – Turf produces organic matter in the upper rootzone that creates soft, spongy playing conditions. Regular sand topdressing, along with core aeration, improves surface firmness and resiliency.

How long do aerated greens last?

I would steer clear for 2 weeks, especially if there are better options.

Does Spike aeration work?

Does spike aeration work? Spike aeration works but provides short-term results because when you push the aerator into the soil, it pushes soil down and to the sides instead of removing the thick thatch that is causing compaction. With time, the soil will readjust and close the small holes you made in the ground.

Do golf courses use liquid aeration?

Patented solution is the most powerful liquid aeration available and is used on the best golf courses, stadiums, and resorts worldwide.

Why do golf courses need aeration?

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: 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.

How does a golf green aerify?

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.") Air and water are thus infused into the ground at root level, and space opened up for new root growth. The holes left behind are filled ...

What is aeration in golf?

Think of golf course aeration as preventive maintenance: It's the (typically) annual process of punching little holes into greens (and sometimes fairways) that opens up growing room for grass roots and helps keep the turfgrass healthy. (It's also called "aerification.")

What is topdressing in golf?

The holes left behind are filled with sand in a process called "topdressing.". Once topdressed, a course is said to have "sanded greens.". The greens are left alone for a few days (although golfers may still play them) and the grass allowed to grow. The topdressing gradually disappears as watering takes place.

How long does it take for a green to get back to normal after topdressing?

The actual coring of the greens is a quick process, but from the time of the coring until the greens are somewhat back to normal is about a weeklong process. Signs of the aeration holes may remain on the putting greens for longer after that.

Where is the ball placed on the putting green?

The most to-the-point part of that local rule is this: "On the putting green, a ball that comes to rest in or on an aeration hole may be placed at the nearest spot not nearer the hole that avoids the situation.". Because such a local rule would be of limited duration, it would not be printed on the scorecard.

Is an aeration hole considered an abnormal ground condition?

The answer is a qualified yes, with an exception possibly provided through a local rule. Aeration holes do not qualify as an abnormal ground condition, because the governing bodies specifically say they do not qualify as "ground under repair" in Decision 25/15: "Q. Is an aeration hole a hole made by a greenkeeper within the meaning ...

How often should I aerate my greens?

This is typically done one to three times a year, depending on the course, the type of greens, and in what part of the country they are located. "The practice of core aeration is done when the grass is growing the most aggressively, so they can have the quickest recovery time," Moeller said.

How long does it take for a green to recover after core removal?

That improves drainage and air exchange for the plants. It can take up to a couple of weeks for the greens to recover, but these procedures are critical for the long-term health of the greens.

Should golfers know before they practice?

Letting golfers know before they show up to the course should probably be the minimum practice, and most courses are trying to do that. How courses and clubs communicate this to golfers varies, of course.

Do you putt on greens that have been aerated?

Most golfers know the importance or aerating greens. Even if they don't understand why, they know it's necessary. Still, no one likes to putt on greens that have been recently aerated, especially a deep-tine aeration with core removal and top dressing. Trying to putt over holes is frustrating at best, and often golfers who do play in such ...

Why do golf courses need aeration holes?

Aeration holes filled with sand topdressing will allow excess water from the soil to evaporate, promote root development and improve drainage. The word aeration stimulates negative emotions for many golfers. It may come as a surprise, but golf course superintendents also dislike aeration. After all, the last person who wants to disrupt ...

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.

What happens when you add too much organic matter to your lawn?

Excessive organic matter also inhibits root growth, reduces oxygen levels in the soil, encourages disease and eventually can lead to turf failure. Furthermore, excessive organic matter creates soft surfaces prone to ball marks, foot printing and inconsistent playing conditions.

What is the most effective way to control organic matter and maintain smooth, firm putting surfaces?

Aeration and topdressing are the most effective ways to control organic matter and maintain smooth, firm putting surfaces. Core aeration involves physically removing small soil cores – e.g., 0.5-inch diameter cores – from the turf and is the most common type of aeration.

Why is a golf course aerated?

Aerification (also known as aeration) achieves three important objectives, the GCSAA explains: 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.

Why fill aerification holes with sand?

Filling aerification holes with sand improves drainage and resists compaction. The periodic introduction of sand to a green's top layer can, over time, avoid or postpone expensive rebuilding or renovation of greens. "Finally, growing of turf adds to a layer of organic matter on the surface.

How to prevent thatch buildup?

Topdressing with sand can prevent thatch buildup, and aerification is one of the best ways to reduce an existing layer and prevent an excess of thatch from becoming established. "Other aerification techniques use machines with "tines"; or knives that simply poke holes through the soil profile.

What does it mean when you show up to a golf course?

Showing up to a golf course only to discover that it has recently underdone an aerification process can be a jolt to the system. You were hoping the golf course, and especially its greens, would be in great shape. Instead you find it full of little holes or covered in sand or other topdressing. It's frustrating.

What is aeration in gardening?

Aerification (also known as aeration) achieves three important objectives, the GCSAA explains: 1 It relieves soil compaction; 2 it provides a method to improve the soil mixture around the highest part of a green's roots; 3 and it reduces or prevents the accumulation of excess thatch.

What is the process of aeration?

From the GCSAA's explanation of the aerification process (all excerpts appear here courtesy of the GCSAA): "Aerification is a mechanical process that creates more air space in the soil and promotes deeper rooting, thus helping the grass plants stay healthy.

When is aerification best done?

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.".

Why do you aerate greens?

Aeration comes in when soils are heavily compacted or the turf is thick with thatch. The greens get punched and sanded, and the sand is worked into each aeration hole to improve air and water flow, giving the roots a better chance to drink and breathe. There is, of course, plenty more to the science of sanding.

Why is sanding greens important?

The green might get spongy, or develop brown spots, or become vulnerable to scalping during mowing. Sanding helps protect against all that. That’s not all, Kidd says. Sanding also improves drainage and helps level out the green, creating smooth, consistent putting surfaces, and firm, fast conditions year round.

What is golf sand made of?

Golf course sands are different. They are made of round particles “resembling a bucket of balls with large pore spaces between each ball ,” Kidd says. They promote good drainage, and healthy air and water circulation.

Do superintendents sand putting surfaces?

Superintendents don’t sand putting surfaces simply to annoy you. They do it for the long-term health of the greens. That’s the gist. But since you’ve been inconvenienced, you deserve to know precisely why.

Is sanding a science?

As you can probably see, there’s a science to sanding, and on golf courses today, Kidd says, that science is “very precise.”. When you sand and how much sand you use is critically important. Sand too heavily at the wrong time of year, and you risk a range of problems. It’s best to do the work in good weather, Kidd says.

Do you need to aerate your turf?

If the soil is heavy, you might need to aerate to keep your turf healthy. The staff at a respected lawn care store should be able to help you make smart choices. You might not wind up with a patch of grass as pure as a putting green, but you’ll have a pretty sweet place to chip and pitch.

Do you need to sand your lawn?

Depending on how you use your own yard, you might never want or need to sand it. But if you do, be sure to use the right sand, in the right amounts, at the right time.
