Where does Augusta get their sand?

The white sand in the bunkers at Augusta National comes from North Carolina, namely the Spruce Pine mining area of the northwestern portion of the state, near the Blue Ridge mountains. That region has been producing quartz and feldspar, which is a slightly less pure version of quartz, since the Colonial Era.

Bunkers (or sand traps) are shallow pits filled with sand and generally incorporating a raised lip or barrier, from which the ball is more difficult to play than from grass.

Why do greenkeepers put sand on the greens?

How do golf courses keep weeds out?

Golf courses also adhere to a regular schedule of applying pre-emergent herbicides as well as weed killers and fertilizer. The key behind pre-emergent herbicides is weed prevention. Of course there are no “magic bullets” that keep all weeds out for the entire growing season.

Why do golf courses punch greens?

The goal of aerating greens is twofold. First, the process helps to reduce the likelihood that the soil will compact on the greens. The second goal is to get air circulating down through the soil and the roots. The hope is that this will keep everything healthy for many years to come.

Sand comes from many locations, sources, and environments. Sand forms when rocks break down from weathering and eroding over thousands and even millions of years. Rocks take time to decompose, especially quartz (silica) and feldspar.

What makes sand tan?

The tan color of most sand beaches is the result of iron oxide, which tints quartz a light brown, and feldspar, which is brown to tan in its original form. Black sand comes from eroded volcanic material such as lava, basalt rocks, and other dark-colored rocks and minerals, and is typically found on beaches near volcanic activity.

What is Rachel Carson saying about the sand beneath you?

Bermuda's preponderance of pleasantly pink beaches results from the perpetual decay of single-celled, shelled organisms called foraminifera. Less common but no less inviting beaches, devoid of quartz as a source of sand, rely on an entirely different ecologic process.

What is the porous matrix in a sand bunker?

The porous matrix is spread across the entire sand bunker on top of the aggregate layer, including the contoured sides of the sand bunker. The porous matrix is permitted to cure in place within the bunker, therein reinforcing all surfaces of the sand bunker. Lastly, a covering of sand is applied over the porous matrix.

What is a sand bunker?

The aggregate is gravel having an aggregate size large enough to avoid displacement from rain and irrigation spray. A porous matrix is placed upon the first layer.

What is the first layer of drainage in a bunker?

The first layer placed upon the ground is a layer of loose stone aggregate. The aggregate is gravel having an aggregate size large enough to avoid displacement from rain and irrigation spray.

What is a porous matrix?

A porous matrix is placed upon the first layer. The porous matrix is made from gravel aggregate that is coated with a binding agent, such as asphalt, tar, or cement. The binding agent is added in amounts only sufficient to bind the aggregate.

Do you have to respread sand in a golf course?

The groundskeeper of the golf course must therefore periodically respread the sand in every sand bunker, especially after a heavy rain. If a sand bunker is built without a lining, sand tends to easily wash off of the face of the bunker during rainfall events and wash to the bottom of the bunker.

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.”.
