Phosphoric acid in form of floats. 2 Ammonia in form of dried blood. 3 Am- 

 monia in form of tankage. 4 The percentages of fertilizer are indicated in the 

 order of ammonia, phosphoric acid and potash. Thus 0-20-0 means ammonia 

 per cent, available phosphoric acid 20 per cent and potash per cent. Except as 

 indicated otherwise in the footnote one-third of the ammonia is in the form of 

 nitrate of soda and two-thirds as sulphate of ammonia; the phosphoric acid as 

 acid phosphate and the potash in water soluble form.
