CONTROL SERIES No. 65 

 (b) Tonnage of Unmixed Fertilizing Materials. 



Of the 38,359 tons of complete fertilizer guaranteed to contain 14 per cent 

 or more of available plant food, 77.4 per cent was furnished by 10 grades 

 and 170 brands. Double and multiple strength grades totalled 1,004 tons 

 and 22 brands — 203 tons less than during the previous year. 



Of the mixed fertilizer sold, 96.75 per cent contained 14 per cent or over of 

 available plant food, compared with 90.75 per cent in 1931. The tonnage of 

 superphosphates with potash sold during the year was negligible, being only 

 one-tenth of 1 per cent of the total tonnage of mixed goods. 



There were 2,613 tons less of low-analysis (less than 14 per cent of available 

 plant food) complete fertilizers sold than in 1931. The 5-3-5 grade, com- 

 prising 10 brands, furnished about 67 per cent of the tonnage of these low- 

 analysis goods. About 92 per cent was furnished by 3 grades, comprising 12 

 brands. 



The tonnage of unmixed materials was distributed as follows: nitrogen 

 products, 47.61 per cent; phosphoric acid products, 18.99 per cent; potash 

 products, 4.32 per cent; tankage, fish, bone, tobacco stems, wood ashes, and 

 nitrate of potash, 20.01 per cent; and miscellaneous, 9.07 per cent.
