He probably meant 1 Million pounds, that would be 91.87 pounds per cubic
foot. That's a density of a little less than 1.5 were water has a density
of 1. So it would sink, not float. The density is much more realistic.
Three inches of compost seems like a lot to add for coverage, though I
don't know much about gardening. Seems pretty rich, especially if it's
done every year.
I wonder if that 3 inches is correct, and if it's ever done on a large
scale.
