(b) Tonnage of Unmixed Fertilizing Materials. 



' The number of brands is omitted where it is less than five. 



A study of the preceding tables shows: 



1. About 66 per cent of the total tonnage sold was mixed goods, and 34 per 

 cent unmixed fertilizing materials. (In 1925 the proportion was 72 per cent mixed 

 and 28 per cent unmixed.) 



2. Of the 39,100 tons of mixed fertilizer sold, about 99.7 per cent were complete 

 fertilizers and .3 per cent were ammoniated superphosphates and superphosphates 

 with potash. 



3. Of the 38,996 tons of mixed complete fertilizers, about 96.9 per cent were 

 high-analysis (14 per cent or over of available plant food), and 3.1 per cent were 

 low-analysis fertilizers (less than 14 per cent of available plant food). This shows 

 an increase over 1925 of 1.4 per cent in favor of the high-analysis goods. 



4. Of the 37,783 tons of high-analysis complete fertilizers, 87 per cent were 

 furnished by 20 grades and 216 brands, and about 80 per cent were furnished by 

 12 grades and 182 brands. 



5. Seventy-seven per cent of the low-analysis complete fertilizers was furnished 

 by one grade (2-8-2) comprising 15 brands. There were 787 tons less of low- 

 analysis complete fertilizers sold during the season than for the previous year. 



6. The tonnage of fertilizer simples was distributed as follows: nitrogen prod- 

 ucts, 56 per cent; phosphoric acid products, 39 per cent; and potash products, 

 5 per cent.
