1 ton = 2,000 lbs. 1 cubic yard of dry sand
= 2,700 lbs. (1.35 tons) 1 cubic yard = 27 ft³, 3x3x3 Perm O² 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% PermOPore and 80% dry sand is the following: The bulk density of PermOPore 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 So, for
an 80/20 mix, you could round off and say that you need 2 tons of
PermOPore and 20 tons of dry sand for a total of 22 tons of greensmix As a general rule, Powell Gaines from Tifton Physical Soil Testing Laboratory has provided the following mix amounts for PermOPore and dry sand: 90/10 Mix = 108 lbs.
PermOPore per 1.35 tons of dry sand Other soil amendments will vary according to their bulk density. You can contact Powell Gaines at 2293827292 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 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. 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. 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.
