It is important that the small portions of 
earth be fertilized in the same proportion as is 
here given for the field, so to 72 pounds of dry, 
finely pulverized soil, add one ounce of any one 
of these fertilizers. Mix very thoroughly and 
pass it through a sieve at least twice. This is 
still much too strong for use, so take one ounce 
of this fertilized soil and add it to five pounds 
more of soil, mixing and sifting as before. Then 
you have soil and fertilizer mixed at the rate of 
200 pounds to the acre. For testing larger ap- 
plications, make your first mixture with propor- 
tionally larger quantity of fertilizer. 
For mixing lime with soil, take only 114 ounces
