The typical range of aluminum in soils is from 1 percent to 30 percent (10,000 to 300,000 mg Al kg-1) (Lindsay, 1979 and Dragun, 1988), with naturally occurring concentrations varying over several orders of magnitude.
So, rough guessing, top soil weighs between 2,100 - 3,000 lbs per cubic yard. If the answer is 1%, that's 21 lbs of Aluminum per cubic yard; so I am to believe that 5x (or an additional 4%) Aluminum per cubic yard (105 - 21 lbs) or 84 lbs of Aluminum per cubic yard has been airdropped across the fields in America? It's even more impossible when you throw the numbers closer to 30% range.
