Can someone check my math? (cornell peat-lite mixture)

[Anonymous]

Starting seedlings and would like to make this recipe, however it is in cubic yards.

I am dividing by 100.

/100 input output
peat moss .5 to .005 (cu yard) = 4 quarts
vermiculite .5 to .005 (cu yard) = 4 quarts
lime stone lb 5 to .05 (lb) = 22.6 grams
super phosphate 0-20-0 1.5 to .015 (lb) = 6.8 grams
potassium nitrate 1 to .01 (lb) = 4.5 grams
