Thatch refers to the layer of organic matter that is accumulated below the turf. It is a combination of dead and living plant matter which include roots, stolon, shoots, stems and leaf tissues. A thatched turf will cause the ground of your golf course to be soft and spongy, thus affecting the playability of your course.
What happens when there is too much thatch on a golf course?
When too much thatch is present, the turfgrass environment changes and the way the golf ball interacts with the surface will change. You’ll find balls don’t roll evenly, even across the same green. Thatch is a layer of dead vegetation that sits between the green vegetation you see and the soil.
What is the effect of thatch on the Greens?
These large accumulations of organic matter (thatch) were having a dramatic effect on the playability of the greens, especially in periods of heavy rainfall. This, coupled with footfall, resulted in uneven, foot-marked greens that were not conducive to producing a quality putting surface.
What is thatch and how can you prevent it?
Thatch is a layer of dead vegetation that sits between the green vegetation you see and the soil. It’s caused when the grass is growing and being cut faster than it can be decomposed.
What is thatch and Tining in grass?
(Thatch is a layer of grass stems, roots, and debris that settle and accumulate over time.) A thin layer is acceptable but too much thatch will hold water like a sponge. Tining also removes accumulated fibre in the grass’s root zone.

How often do golf courses Dethatch?
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.
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 often should you aerate golf greens?
one to three times a yearIt 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.
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.
Why do they put sand on fairways?
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 does top dressing a green do?
Topdressing improves putting greens smoothness, increases firmness and dilutes thatch. Thatch is a layer of dead and living plant material just below the turf surface.
How often do golf courses sand the greens?
every seven to 28 daysWithout regular sand topdressing and aeration, excess organic material will create soft, spongy putting surfaces that hold too much water. At most golf courses, topdressing sand is applied every seven to 28 days.
How often should you top dress greens?
2014a). Topdressing every 7 to 14 days also is more common in successful ultradwarf bermudagrass putting green management programs (Lowe, 2013; O'Brien and Hartwiger, 2014).
What happens if you don't aerate greens?
Without aeration, organic matter (i.e. bacteria and other plants) build up on the surface of the turf. This increase in the concentration of plant matter can prevent water from draining into the soil and can reduce the amount of oxygen that reaches the roots, which ultimately limits growth.
How do you put bumpy greens on putts?
__-- Play less break, and hit the putt firmer. __Slower, bumpy greens simply don't break as much because the ball is rolling faster through most of the putt. Putts that roll slower (like on faster greens) will break more because gravity can have more effect. -- Concentrate on hitting the putt solid.
How often should you hollow tine?
Those with hard or clay soil should be aerated once a year as they have more difficulty getting air and water to the roots. For all other types of soil and lawn you should aerate at least every 3 years, but more frequent if the grass is looking unhealthy or not growing well.
Does Bermuda grass need dethatching?
Bermuda grass must be dethatched at the beginning of the growing season, in spring. This allows the grass to recover from the stressful dethatching process and return greener and fuller than before. Dethatch in March or April. Dethatch after spring green-up.
When should I dethatch Bermuda grass?
Dethatching should be performed from early July through the end of August during weather that promotes rapid bermudagrass recovery. Dethatching during this time will facilitate overseeding preparation practices due to more upright bermudagrass growth and less thatch.

How do you dethatch Bermuda grass?
To remove thatch from your bermudagrass lawn, you will need either a thatching rake or a vertical mower. A thatching rake works well from small lawns, while a vertical mower works well for bigger lawns. Adjust the mowing blades depending on the thickness of the thatch layer.
What is thatch in turf?
Thatch is defined as partly decomposed or undecomposed organic matter exclusively of plant origin.
How does organic matter affect golf course?
Organic matter plays a pivotal role in golf course and general turf management through its influence on most processes that collectively determine 'turf health' or 'turf quality'. The changes in organic matter arising from turf management can critically affect the performance and sustainability of golf greens.
Which layer of soil contains the highest level of lignin?
The forest litter contained the highest level of lignin, followed by the thatch layer from soil-based green and the pasture soils (Figure 3). Based on the lignin content it could be argued that the thatch material from the soil-based green is less degradable compared to that of sand-based green.
How does aeration help with thatch?
By getting air into the thatch, soil life would be increased and this, in turn, would help break the thatch down .
What is compost de thatcher?
The Compost De-Thatcher is a high-quality fertiliser made of a unique blend of slow-releasing nitrogen, naturally occurring soil digesting microbes, and powerful enzymes that work in breaking down components of organic matter in thatch . These elements work together to break down the high ratio of lignin and cellulose fibres in turfs. Additionally, the specific microbes formulated into the Compost De-Thatcher produce significant quantities of protease and cellulase that digest protein found in thatch and other organic compounds. Bacillus is also among the beneficial bacteria which produces cellulase, amylases, lipases, xylanases, and pectinases. They aid in breaking down organic matter into valuable nutrients. The right fertiliser can maintain the right amount of thatch, keeping your overall golf course healthy. Interested to know more about how the Compost De-Thatcher can benefit your golf course? Please contact Putra Fajar ([email protected]) for more details.
What happens when you reduce thatch in your soil?
When the thatch within the soil profile is reduced, the locked-up nitrogen can start to release, and the greens can then commence self-feeding. This self-feeding would mean a reduction in nitrogen inputs, and a small cost saving can be made.
How does footprinting affect golf?
Footprinting on the golf course might even be more noticeable, thereby causing unevenness on the ground. Moreover, excessive thatch and organic matter will affect the growth of grass there. It will cause the greens to be saturated in the upper root-zone, reducing oxygen uptake and causing root decline. In other words, it will affect the firmness of ...
What is thatch in golf greens?
Essentially, maintaining a good turf greatly looks into reducing and maintaining a good level of thatch. Thatch refers to the layer of organic matter that is accumulated below ...
Why do you aerate grass?
It is done when the soil beneath the surface of the greens has become compact, which could suffocate the grass roots. In other words, aeration is essential to break the thatch layer on your turf. This will aid the movement of important nutrients within the thatch and soil zones, while also creating deeper root systems.
What are the main contributors to thatch?
One of the main contributors to thatch is shoot and stem growth. To ensure that stem growth is not excessive, nitrogen inputs can be evaluated to decide on the delivery of nutrients in a much more controlled manner.
What is thatch in Bermuda grass?
Thatch is defined as the living and non-living material located between green turfgrass leaves and the underlying soil. Bermudagrass turf in the Florida Region accumulates a large amount of organic matter, and it is best to use the terms "thatch" and organic matter or "mat". In this case, thatch is the layer of turfgrass stems located just below the green leaf canopy and mat is the dark organic material located under thatch. Some thatch and mat is necessary for surface resiliency and nutrient retention, but excessive thatch can cause major issues with playability and turf health.
Why are my Bermuda grass greens saturated?
It causes greens to remain saturated in the upper rootzone, reducing oxygen uptake and encouraging root decline.
When is aggressive turf cultivation necessary?
Unfortunately, aggressive cultivation programs are necessary to maintain premium playing conditions and these practices must take place during periods of optimum turf recovery (i.e. the summer months). This generally equates to some type of cultivation occurring during much of the summer season.
How deep is a loss on ignition test?
After a physical examination of the greens profile, it was decided to carry out a loss on ignition test on three greens in 20mm zones to a depth of 80mm. These tests would give us a tangible benchmark of the amount of organic matter within the greens and where it was within the soil profile. From these tests, targets could then be set for its reduction. The three greens chosen were perceived, at the time, to be a standard, a wet and a dry green.
Why are good playing surfaces important in golf?
Good playing surfaces are a prime requirement for golf clubs to attract and retain members and , without that in place, members will start to chunter and the word will be out.
Is Sandwell Park hollow tined?
It's been decided that, in 2014, only the softer areas of the greens will be hollow tined. The remaining will continue to be reduced by less disruptive methods such as verticutting, dressing and solid tine aeration.
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.
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.
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.
Does sanding help with thatch?
For starters, Kidd says, sanding helps break up thatch, a layer of organic material that builds up over time in the upper root zone. Too much of that stuff is not a good thing. If levels of thatch exceed roughly a half-inch, Kidd says, “the greens will suffer during extremes of drought and wet periods.”.
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.
Why do I need to tin my grass after coreing?
A thin layer is acceptable but too much thatch will hold water like a sponge. Tining also removes accumulated fibre in the grass’s root zone. It allows for the exchange of a poor soil for a better one through top dressing. That’s why the greens are normally covered in sandy top dressing immediately after they’re cored.
Why do I need hollow tining?
Hollow tining allows the compacted turf to expand and air and moisture to be more easily absorbed. The coring helps address the problem of thatch. (Thatch is a layer of grass stems, roots, and debris that settle and accumulate over time.) A thin layer is acceptable but too much thatch will hold water like a sponge.
What is slitting in turf?
Slitting is another method of aerating the turf and counteracting thatch. Deep slitting is normally carried out through the winter when the ground is softer and more receptive. It’s done with blades that penetrate from 125 to 300 mm. These will be attached to a machine pulled by a tractor.
When to hollow tine golf clubs?
So the best time to hollow tine is late August/early September, but this coincides with the playing season at most clubs.
Can you use solid tining to aerate?
Not quite. Solid tining doesn’t go as deep as hollow tining. It’s useful for aerating the upper level of the root zone but it won’t relieve the problem of compaction. It can be carried out at any point through the year and is particularly good where there is sandy soil that doesn’t need much compaction relief.
When is the best time to hollow tine?
So the best time to hollow tine is late August/early September, but this coincides with the playing season at most clubs. It’s a difficult balancing act for greenkeepers. Some clubs will look to hollow tine very early in the spring season. Continues below.
