A study of the foregoing tables shows : — 



1. Of the total tonnage sold, 72 per cent consisted of mixed goods and 28 per 

 cent of chemicals and unmixed fertilizer by-products. 



2. Of the 47,671 tons of mixed goods sold, 98.5 per cent were complete fertilizers 

 and 1.5 per cent ammoniated superphosphates and superphosphates with potash. 



3. Of the 46,961 tons of mixed complete fertilizers, about 84 per cent were high- 

 analysis (14 per cent or over of available plant food) and 16 per cent low-analysis 

 fertilizers (less than 14 per cent of available plant food) . 



4. Of the 39,415 tons of high-analysis complete fertilizers, 96 per cent were furnished 

 by 35 grades and 222 brands, and 86 per cent were furnished by 14 grades and 188 brands. 



5. Of the 7,546 tons of low-analysis fertilizers, 93 per cent were furnished by 11 

 grades and 98 brands. 



6. In case of the ammoniated superphosphates and superphosphates with potash, 

 of the 710 tons sold, about 53 per cent were low-analysis and 47 per cent high-analysis 

 goods; about 81 per cent of the high -analysis tonnage was furnished by 4 grades 

 and 11 brands, and 53 per cent of the low-analysis tormage was furnished by 2 grades 

 and 3 brands. 



7. The tonnage of chemicals and crude stock materials was distributed as follows: 

 nitrogen products, about 47 per cent; phosphoric acid compounds, 40 per cent; potash 

 compounds, 13 per cent. 



Over 43 per cent of the total tonnage of mixed fertilizers was derived from grades 

 recommended for the Eastern United States by the Soil Improvement Committee of 

 the National Fertilizer Association; and in addition about 26 per cent of the total 

 tonnage deviated by 1 per cent only in nitrogen, phosphoric acid or potash from 

 grades thus recommended.
