1 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 sul- 

 phate of ammonia; the phosphoric acid as acid phosphate and the potash in water 

 soluble form. 



2 Phosphoric acid in form of floats. 



3 Ammonia in form of dried blood. 



4 Ammonia in form of tankage.

 Arranged in Triangular Diagram. 



The letters N, P and K indicate the parts of the triangle 

 where ammonia, available phosphoric acid and potash are re- 

 spectively at their maximum amounts. The upper numbers 

 above each * are the plot numbers. The numbers arranged in 

 threes and connected by - give the composition of the fertilizer 

 used. The numbers below the * give the yields per acre ex-
