   Hi Judy, those numbers represent the number of pounds of the element
   per 100 pounds of the mixture. The rest is either plain pulverized
   rock, or pulverized rock treated with sulfuric acid to release the
   elements more quickly. Therefore 10-20-10 has exactly twice as much
   as 5-10-5 of essential elements. As always, though, follow package
   directions. (Big copout grin)
