Bunkers always have been considered more expensive to maintain than turf, although in the old days, raking them three times a week versus mowing rough three times a week shouldn't have cost substantially more. Nowadays, higher bunker standards require daily hand-raking and edging and weekly leaf/clipping blowing.

How much sand should be in a bunker?
The sand particles in the finer fraction – i.e., less than 0.25 mm in diameter – are more prone to wind erosion. At windy sites, the USGA recommends more than 80% of the bunker sand should be between 0.25 and 1 mm and 10%-20% should fall in the coarser fraction from 1-2 mm in diameter.

What makes bunker sand good?
Golf Association considers a list of eight factors when selecting bunker sand: particle size, particle shape, crusting potential, chemical reaction and hardness, infiltration rate, color, penetrometer value and playability. Depending on location and climate, how these factors are ranked vary slightly.
What sand is used for bunker sand?
For many years, selecting bunker sand involved calling the local sand pit. Superintendents were often told, “We have mason sand, brick sand and concrete sand. I think what you want is our mason sand. That stuff would work great for you.” Mason sand might or might not be desirable sand for bunkers, but in the current golf climate, the days of calling the local sand pit are over. There are few places in the United States that have natural sand deposits that meet specifications for great bunker sand. Most premium bunker sand is manufactured in only a few locations throughout the country. These manufactured sands, along with a few rare natural deposits, make the process of finding great bunker sand difficult and expensive.
What are the issues with bunkers?
The amount of sand in a bunker also can be an issue. Golfers need to be reminded sand bunkers are a hazard, but at the same time, bunkers need to be a fair hazard.#N#The major issues with bunkers are sand quality and playability, and obtaining quality bunker sand, which isn’t easy.
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.
Is Mason sand good for bunkers?

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.
How to tell if sand is firm?
The uniformity coefficient (Cu) can be useful for predicting the relative firmness of sand by identifying if the material is narrowly or widely graded. A narrowly graded sand contains many particles of similar size and will have a relatively low Cu. Such material is more likely to produce buried lies and is more prone to erosion. Conversely, a widely graded sand is one that has particles of many different sizes and will generally produce firmer conditions due to the greater tendency for the sand to pack together. As a guideline, the Cu should range between 2.0-5.0. In a study by Bigelow and Hardebeck (2004), no meaningful relationship was detected between the Cu and the modified-penetrometer readings used for measuring firmness. However, Crum et. al. (2003) found a strong correlation between the Cu and bearing capacity – a measurement of material strength – in their study “ Agronomic and Engineering Properties of USGA Putting Greens .” The researchers used a modified California Bearing Ratio testing device to quantify the firmness and stability of sand rootzone mixtures for putting greens. When the Cu increased from 1.8 to 3.0, bearing capacity doubled. While this test is not used to evaluate bunker sands, it demonstrates the value of the Cu for predicting material stability in this study.
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.
What is the shape of sand?
Sand particle shape is just as critical as the particle size distribution and is characterized by the degree of angularity and sphericity. Sphericity is an indication of shape. Round particles have high sphericity and oblong particles have lower sphericity . Angular sands resemble a cut piece of glass with sharp, jagged edges, while a well-rounded sand is smooth and looks more like a potato. Figure 1 shows the six classifications used to describe angularity and the three classifications that describe sphericity. Selecting sands that range from very angular to subangular and have low to medium sphericity will likely produce desirable bunker playing conditions. Well-rounded, rounded and high-sphericity sands lead to soft conditions and buried lies.
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.
