1 ton = 2,000 lbs.

1 cubic yard of dry sand = 2,700 lbs. (1.35 tons)
A 24 ton truck load of dry sand = 17.78 cubic yards

1 cubic yard = 27 ft, 3x3x3

Perm O Pore as an example of a greensmix percentage with dry sand for your next Drill & Fill

An easy way to calculate an 80/20 greensmix with 20% Perm-O-Pore and 80% dry sand is the following:

The bulk density of Perm-O-Pore is .58 and test results state that the bulk density of the dried sand you are using is 1.47 and you know that you can get a 24 ton truck load of greensmix at a time.

.58 1.47 = .395
.20 (20% Perm-O-Pore) x 48,000 (24 tons) = 9,600 lbs.
9,600 lbs. x .395 = 3,792 lbs. of Perm-O-Pore needed
48,000 (24 tons) - 9,600 = 38,400 lbs. or 19.2 tons of dry sand needed

So, for an 80/20 mix, you could round off and say that you need 2 tons of Perm-O-Pore and 20 tons of dry sand for a total of 22 tons of greensmix
or
2.17 tons of Perm-O-Pore and 22 tons of dry sand for a total of 24.17 tons of greensmix.

As a general rule, Powell Gaines from Tifton Physical Soil Testing Laboratory has provided the following mix amounts for Perm-O-Pore and dry sand:

90/10 Mix = 108 lbs. Perm-O-Pore per 1.35 tons of dry sand
85/15 Mix = 172 lbs. Perm-O-Pore per 1.35 tons of dry sand
80/20 Mix = 242 lbs. Perm-O-Pore per 1.35 tons of dry sand

Other soil amendments will vary according to their bulk density. You can contact Powell Gaines at 229-382-7292 to find out what research he has done on other soil amendments and also check out their website at www.tiftonsoillab.com

Estimating tons of material (sand, gravel, greensmix) to cover a given area
1.  Area in square feet  x  desired depth (feet) = cubic feet
2.  Cubic feet    27 = cubic yards
3.  Cubic yards  x  1.3 = tons
4.  Tons  x  (100% + percentage needed for waste) = tons required (an extra 10-20% is usually allowed for waste in handling and compaction of mix)

For Example: You are doing a Drill & Fill aeration using a 1" drill bit and will use .25 cu.yds. of dry sand p/1,000 sq.ft. to 100,000 sq.ft. of greens, you would need how many tons?

.25 cu.yds.  x  100 (100,000 1,000) = 25 cu.yds.
25 cu.yds.  x  1.3 = 32.5 tons
32.5 tons  x  .10 (waste %) = 3.25 + 32.5 = 35.75 tons needed

For Example: You want to add 1/16" of topdressing to 100,000 sq.ft. of greens, you would need how many tons?

1.  100,000  x  .005 (.0625" 12") = 500 cu.ft.
2.  500 cu.ft.    27 = 18.5 cu.yds.
3.  18.5 cu.yds.  x  1.3 = 24.1 tons
4.  24.1 tons  x  .10 (waste %) = 2.4 + 24.1 = 26.5 tons needed

For Example: You want to add 16" of greensmix to 100,000 sq.ft. of new greens, you would need how many tons?

1.  100,000  x  1.33 (16" 12") = 133,000 cu.ft.
2.  133,000 cu.ft.    27 = 4,925.9 cu.yds.
3.  4,925.9 cu.yds.  x  1.3 = 6,403.7 tons
4.  6,403.7 tons  x  .10 (waste %) = 640.37 + 6,403.7 = 7,044.1 tons needed
