Dryject by the Numbers

Two questions keep coming up about Dry-Ject

 

1. How long did it take?

 

It took three (3) machines from 7am to 6pm to finish all 19 greens (Putting Green and 1-18.)  Three people work with the machine at all times.  The operator who works for the company that owns the machines and two of our crew members, who keep the hopper full (green bin) while the machine is in action.

2. How much sand was used?

The non-specific answer is a lot, but being a numbers guy even I wanted to know a specific total.

The total area done with Dry-Ject was 123,000 square feet.  We knew that the sand pile had 62 tons in it before the day began and over half the pile was gone at the end of the day.  Over 31 tons of sand was injected into the profile.  That's over 500 pounds per thousand square feet or nearly 11 tons per acre.  (A dump truck holds on average 31 tons of sand per delivery.)

"How much was put out on fairways?"
 
That's the question I thought to myself immediately.  I ordered 14 truckloads of sand to be used for topdressing.  When the week was over the storage bin was empty.  The golf course has 27 acres of approaches, fairways, and tees.   
Using a 31 ton average per truckload over 16 tons of sand per acre was incorporated into the profile.
