Why is sand applied to putting greens?
Why Is Sand Applied To Putting Greens? March 17, 2017 By USGA Green Section Light and frequent sand topdressing creates smooth, firm putting surfaces. For most, there are three primary characteristics that constitute a quality putting surface: (1) a smooth surface, (2) a firm surface and (3) healthy turf.
What type of sand is best for golf balls?
Therefore, highly angular sand with low sphericity will obtain the best penetrometer reading and offer the best resistance to compression from the golf ball. This translates into a low tendency for a ball to bury in the sand, which minimizes the dreaded fried egg lie.
Is sanding the greens worth it?
Yes, it is. But think of the big picture. Not everything is always just about you. 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. What, in particular, are the benefits of sanding?
Is there a science to sanding a golf course?
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.
What kind of sand do they use at golf courses?
While silica sand is generally preferred over calcareous sands due to its resistance to chemical weathering, many golf courses have been using calcareous sands successfully in bunkers for many years.
What does putting sand on greens do?
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.
What soil is used for golf greens?
SandSand particles are the largest and have the least surface area in a given volume of soil, which gives them the lowest adhesion strength. This is why sands drain well and are the most desirable soil for golf courses.
What kind of sand do golf courses use to top dress?
One type of sand can be used for aeration and topdressing when playability is not a priority – e.g., using a coarse sand to topdress greens prior to winter dormancy or during overseeding. Another, less coarse sand could be used for routine topdressing when minimizing disruption to playability is important.
How often should greens be sanded?
At most golf courses, topdressing sand is applied every seven to 28 days. Ultimately, the appropriate application rate and interval of sand topdressing depends on the rate of turf growth and the overall putting green management program.

Therefore, whiter sands generally have a shorter useful life. Depending on expectations for aesthetics, a brilliant white sand may only last three to five years. Depending on expectations for aesthetics, a brilliant white sand may only last three to five years.
What are the common scenarios for bunker sand?
Common Scenarios. 1. Selecting bunker sand for a wet climate. There is a paradox between selecting bunker sands that have a high enough infiltration rate to handle heavy rain events yet remain firm enough to encourage inbound golf balls to bounce from the impact point.
What are the characteristics of bunker sand?
There are nine key bunker sand characteristics that can be tested in a laboratory: particle size distribution, particle shape, coefficient of uniformity , angle of repose, penetrometer reading, infiltration rate, crusting potential, chemical reaction and color. The soil moisture release curve (SMRC) and moisture column tests will also be discussed. The following text will summarize these characteristics and how they are tested, and offer new perspectives based on current challenges observed in the field.
How many bunker sands were collected in 1985?
1. Particle size. In 1985 and 1986, USGA agronomists cooperated with golf courses across the United States to assess bunker sand quality and collected a total of 42 bunker sands for laboratory testing.
How much infiltration is needed for bunker sand?
The physical soil testing laboratory community has suggested that the minimum infiltration rate for bunker sand is 20 inches per hour, which was based on the 20-24 inch per hour infiltration rate guideline in the 1993 USGA Recommendations for a Method of Putting Green Construction. However, in my experience testing bunker sands on golf courses, I’ve seen that infiltration rates often decrease significantly – e.g., from 22.8 to only 7.5 inches per hour – in just two to three years! Silt and clay from wind-blown dust, organic debris from clippings, leaves from trees or shrubs, algae growth and soil contamination all can decrease infiltration rates. Bunker sands that initially drain from 30-100 inches per hour should work well, depending on the climate and site conditions.
How many mm of bunker sand should be in a bunker?
Less than 15% of the bunker sand particles should be in the very coarse fraction, between 1 and 2 mm.
What color bunker sand should I use for a golf course?
However, white sands can cause problems on bright, sunny days, creating significant glare. Slightly off-white ( light tan) might be a better choice.
What is the best shape for bunker sand?
The most desired shape for bunker sand is a particle shape that’s angular. Therefore, it possesses many sharp and well-defined edges and has low sphericity. Sand that’s smooth and has high sphericity isn’t well suited for bunkers. The difference between these two sand types is the p article shape of the angular sand.
What is the most important characteristic of sand?
Particle shape. Once sand is found with the correct particle sizing, the job is only partially finished. Particle shape is the next characteristic that influences a great sand and might be the most important of all. This also is the one characteristic that influences the penetrometer value the greatest.
Where is Troon Golf located?
Troon Golf, which has the Ocotillo Golf Resort in Chandler, Ariz., in its portfolio, implements its support programs when it takes over management of a golf facility. “There’s no silver bullet for turning around a golf course operation,” says Steve Skinner, president of Northbrook, Ill.-based KemperSports Management.
Can round sand compact?
Round sands can’t compact. Therefore, highly angular sand with low sphericity will obtain the best penetrometer reading and offer the best resistance to compression from the golf ball. This translates into a low tendency for a ball to bury in the sand, which minimizes the dreaded fried egg lie. Penetrometer value.
Do all golfers like the same sand?
Unfortunately, not all golfers like the same bunker sand. Tour professionals and most low-handicapped players prefer firm sand, which allows spin to be produced on the ball. A higher-handicapped player, who can’t develop the clubhead speed needed to get through a firm sand bunker shot, prefers softer sand.

How does sand capping affect turf?
The effect of sand capping can often be most striking when reclaimed water is used to water the turf. Reclaimed water generally contains elevated levels of bicarbonates, carbonates, salts, sodium and other materials that can adversely affect turf health, either directly or indirectly. For that reason, good knowledge and understanding of the local conditions is required before it can be decided which quality and what quantity of sand should be added. Using the incorrect sand can affect both the drainage capacity and water retention ability of the soil. Important characteristics for the sand to have are the correct particle size, water retention characteristics and angularity. A soil laboratory can help in identifying suitable sands that perhaps can be expensive but will deliver better performance while using a lower quantity. The soil laboratory can help understanding of the sand characteristics and local conditions which are essential to make a difference.
How effective is sand capping?
Ideal capping depth layer. Sand capping can only be effective if the root system of the grass can root deeply and extensively. Only once this has been tested and established by a soil testing laboratory, is it possible to determine how much sand should be added.
Why is sand capping important?
Sand capping, the art of adding several inches of sand or a high-sand mix to improve the turf growing conditions by increasing the drainage of the surface, has really gained momentum since the start of the century. It has proven to deliver a more consistent surface with a rapid drainage capability that remains firm, even in wet conditions.
Can you build a sand base directly on existing soil?
At present, the USGA doesn’t have specifications for sand-based construction directly atop existing soil. However, studies have shown that the root mass detected within the underlying subsoil can be inversely proportional to sand-cap depth.
