2. Of the 46,328 tons of mixed goods sold, about 99.5 per cent were complete fer- 

 tilizers and .5 per cent ammoniated superphosphates and superphosphates with 

 potash. 



3. Of the 46,088 tons of mixed complete fertilizers, about 87 per cent were high- 

 analysis (14 per cent or over of available plant food) and 13 per cent low-analysis 

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



4. Of the 40,226 tons of high-analysis complete fertilizers, 90 per cent were furnished 

 b}^ 29 grades and 189 brands, and 70 per cent were furnished by 6 grades and 132 

 brands. 



5. Of the 5,862 tons of low-analysis fertilizers, 96 per cent were furnished by 5 

 grades and 49 brands, and 87 per cent were furnished by 3 grades and 44 brands. 



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

 of the 240 tons sold, about 55 per cent were high-analysis and 45 per cent low-analysis 

 goods. 



7. The tonnage of umnLxed fertilizing materials was distributed as follows: nitrogen 

 products, 51 per cent; phosphoric acid compounds, 39 per cent; potash compounds, 

 10 per cent. 



Fortj'-two per cent of the total tonnage of mixed fertilizers was derived from grades 

 adopted as "New England Standard Nine" at a conference of fertilizer manufac- 

 turers, station directors and agronomists held in Boston, December 30, 1922, and 65 

 per cent of the total tonnage deviated by 1 per cent only in nitrogen, phosphoric acid 

 or potash from grades thus recommended. It is worthy of note that the 4-6-10 grade 

 ranied sixth from the highest in tonnage sold, the grades nearest to this in the "New 

 England Standard Nine" being 4-8-6 and 5-8-7. 



The "New England Standard Nine" comprise the following grades: 



0-12-6 4-8-6 



2-12-4 5-4-5 



3-10-4 5-8-7 



3-10-6 8-6-6 



4-8-4 



Deficiency Statistics. 



Serious deficiencies are emphasized on a subsequent page in case of those brands 

 having a conmiercial shortage amounting to $1 or over per ton. In some instances, 

 however, deficiencies in one or more elements have occurred which may have thrown 

 the fertilizer somewhat out of balance, although commercial shortages of a serious 

 nature were prevented by overruns in other ingredients. 



The following table gives a general study of each manufacturer's brands, indicating 

 the seriousness of the deficiencies. The number of brands analyzed and the number 

 approximately equal to the guarantee in commercial valuation are also shown. The 

 data include all mixed goods analj^zed, and the deficiency statistics apply to nitrogen, 

 available phosphoric acid and potash.
