Yay that would be easier 68.42 lb of 0-0-60 plus 31.58 lbs 12-40-0-10S-1ZN.

However I have found that it is cheaper to make the mix with zinc sulfate and S90, as they charge a premium for the mesz. Mesz would have the advantage of getting the zinc more evenly disturbed, since at just a pound of zinc sulfate per acre would leave large gaps between granules.
