Report on Inspection Work of the 



material to be used as a fertilizer shall contain a smaller percentage of 

 nitrogen, phosphoric acid, potash or calcium oxide than is certified 

 in said statement to be contained therein, when such deficiency shall 

 be greater than ten per centum of any one of such constituents unless 

 there be a monetary equivalent in excesses in other guaranteed con- 

 stituents as provided herein; provided such deficiency does not exceed 

 20 per centum of such guarantee in any one constituent point. The 

 basis of values of such constituents necessary in making such compu- 

 tations shall be determined by the commissioner of agriculture." 



It is a matter of interest, as well as of importance, to see how the 

 present law works in practice in comparison with the former. We 

 will make such a comparison based on the analyses of about 1000 

 samples of fertilizers, as given in Bulletin No. 390. We will consider 

 (1st) the number of cases that would appear as violations under the 

 former provisions of the law and the number occurring under the 

 present law, (2nd) the amount and value of the constituents deficient 

 in these samples, and (3rd) some suggestions for remedy of the defects 

 that are shown in the present law. 



Table XXIV. Number of Violations under Former and Present Laws. 



An examination of the table above shows in general that under the 

 present law many cases are not violations which would be such under
