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



A study of the preceding tables shows : 



1. About 72 per cent of the total tonnage sold was mixed goods, and 28 per cent 

 unmixed fertilizing materials. 



2. Of the 44,980 tons of mixed fertilizer sold, about 99.7 per cent were com- 

 plete fertilizers, and .3 per cent were ammoniated superphosphates and super- 

 phosphates vnth. potash. 



3. Of the 44,860 tons of mixed complete fertilizers, about 95.5 per cent were 

 high-analysis (14 per cent or over of available plant food), and 4.5 per cent were 

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

 increase over 1924 of 6.5 per cent in favor of the high-analysis goods. 



4. Of the 42,860 tons of high-analysis complete fertilizers, about 90 per cent 

 were furnished by 26 grades, and 228 brands, and about 76 per cent were furnished 

 by 10 grades and 183 brands. 



5. Of the 2,000 tons of low-analysis complete fertilizers, 91 per cent were fur- 

 nished by 3 grades and 33 brands, and 79 per cent were furnished by 2 grades 

 and 29 brands. 



6. The tonnage of unmixed fertilizing materials, exclusive of pulverized manures, 

 ammonium phosphate, and nitrate of potash, was distributed as follows: nitrogen 

 products, 50 per cent; phosphoric acid compounds, 41 per cent; and potash com- 

 pounds, 9 per cent.
