One square mile is 640 acres.
One square mile is 5280 feet by 5280 feet.
A tractor pulling a 30 foot wide disc plow will requi

5280/30 = 176 passes. That's 176 linear miles to plow the entire 640 acres.

Now the next question is, how much horsepower (fuel consumed) to cover
the 176 miles?

And then there are the herbicide/pesticide/fertilizer/harvest passes also.

Take it away Nick.



300 gallons biodiesel produced per acre.
300 time 640 = 19200 gallons.

Tractor pulling 30' disc plow get @ 4 miles peer gallon
4 times 176 = 704 gallons

19200 over 704 = 27.3
or
704 over 19200 = 4%
