Re: Sand Top Dressing after Aeration I'd go two passes, if you can approximate a 2.5 x 2.5” pattern (most aerators produce a 5x5 for one pass) that's awesome. The sand will fill in the holes and help provide a semi-permanent channel for all the goods to reach the root zone.Mar 30, 2021
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.
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.
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.
What are the factors that affect the quality of sand in golf bunkers?
Additionally, there are many other factors to consider such as drainage, cost, vulnerability to wind and water erosion, crusting potential, chemical stability and color. All these characteristics will influence the quality of the golf experience and are key considerations in selecting sand for your golf course bunkers.
What percentage of silt and clay should be used for golf wedges?
Given the importance of drainage, fine particles must be minimized. The combined silt and clay fractions must not exceed 3%. Excess silt and clay will cause crusting when dry, increase moisture retention and reduce drainage capabilities.
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 is the difference between set up and crusting?
Calcareous sands – those that contain calcium carbonate – and bunker sand containing a combination of silt and clay that exceed 3% are more prone to crusting or set-up. Crusting is a thin layer of hardened sand that forms at the sand surface, while set-up is a layer of hardened sand beneath the surface, both of which may develop during drying cycles. The crusting potential test is performed by spreading a thin layer of sand in a tray, adding a small amount of water, allowing the sand to dry, then inserting a thin spatula in the sand and lifting to observe if a crusted layer formed during the drying process. The set-up test is slightly different and involves scraping off the surface layer of the sand and observing if a cemented layer has formed on the bottom of the tray.
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.

Bunker Sand
In the United States, todays golfers are becoming increasingly more demanding of bunkers that play consistently, drain rapidly, and provide additional beauty to the entire golf course.
What size sand should I use for bunkers?
Particle Size As a general guideline, a sand used in bunkers should be composed of particles with a large majority in the range of O.25-1.00mm. Silt and clay (particles below O.05mm) should be kept to a minimum, since they are associated with surface crusting.
What does a high pH mean in sand?
The pH value provides insight into the chemical makeup of the sand. A sand with an extremely high pH(>8.0) is likely to be strongly calcareous and therefore subject to physical and chemical weathering. Sand particles also can change in shape and size due to mechanical wear.
What is crusting in bunkers?
Crusting is the formation of a layer of dried, stiff sand on the surface of the bunker. Such layers typically are. ;Isto ~ inch in thickness, and they severely decrease the playing quality of the bunker. Sands that are prone to crusting require more frequent raking to maintain good playing quality.
What are the major areas of bunkers?
Generally, there are four major areas that must be considered when evaluating bunkers. These are sand selection, architecture, construction, and maintenance . Selecting the proper sand for bunkers isarguably the most difficult of these four areas. The makeup of the sand strongly impacts maintenance and playing quality.
What is the most important component in the selection process?
The most important component in the selection process is allowing an adequate amount of time to fully evaluate the various factors. WTH THE possible exception of green speed, sand bunkers are the most controversial and discussed features on golf courses, regardless of the golfer's ability.
Does bunker sand end up on the green?
When evaluating the particle size range ofthe sand for bunker use, keep in mind that bunker sand often ends up on the green in surprisingly large quantities. As golfers blast their way free of the hazard, the sand is thrown onto the adjacent green.
Can sand be crushed?
Sand particles that are very soft can be crushed into smaller particles during raking. A soft sand may play and drain perfectly at first, only to degrade in quality as the particles are broken down. Some laboratories now perform a hardness test to deter- mine the likelihood of this type of degradation.
