There is aproximatly 2 million lbs in the top six inches of soil. Therefore 1 part per million = 2 lbs / acre. This varys by soil texture

yep, divide by 2.
except for P (divide by 4.6)
except for K (divide by 2.4)
except for S (divide for 6)
that is, assuming a 6.5-7 inch plow depth. that's where they get the 2 million pounds from. for 9-10 inches deep, you'll divide by 3.
