1 cubic
foot of…
clay and silt =75-100 lbs.
sands =96-110 lbs.
loam =75-100 lbs.
avg. soil =80-90 lbs.
1 acre foot of avg. soil =3,500,000 to 4,500,000 lbs
(
2,000 tons )
An acre-furrow-slice is considered
as the surface soil to a depth of 6 or 7 inches. It is usually considered to weigh about
2,000,000 lbs. for general purposes, but as indicated above the weight will
vary.
The weight of a cubic foot of soil
can be found by this formula:
Bulk
Density x 62.42 = wt. 1 cu. ft.
Weight of
soil (in lbs.) x 62.42
_______________________
= Bulk Density
Volume of
soil (in cu. ft.)
