Dec, 1932] fertilizer inspection, 1932 3 



In Table I are given the grades of complete fertilizers 

 collected, the number of brands found in each grade, the 

 average analysis of each grade and the average retail 

 price per ton. This table is prepared to call the pur- 

 chaser's attention to the greater values to be secured in 

 certain of the higher grades. 



CONFORMITY TO GUARANTEE 



Forty of the 109 brands analyzed were found to contain 

 less than the guarantee of one or more of the three con- 

 stituents. The total number of guarantees on the 109 

 brands was 307, the total number of deficiencies 46, the 

 per cent of the guarantees deficient 15.0. In last year's 

 inspection this figure was 11.7 per cent. The previous 

 year it was 13.0 per cent. Many of the deficiencies were 

 comparatively negligible, the small deficiency in one con- 

 stituent being offset in value by overrun in other consti- 

 tuents. 



A detailed summary of the deficiencies in the 40 brands 

 which failed to meet the guarantees follows:
