INSPECTION OF FERTILIZERS FOR 1911 



The samples of fertilizer for the 1911 inspection, as 

 usual, were collected under the direction of the State Board 

 of Agriculture and turned over to the State Agricultural 

 Experiment Station for analysis. Aside from duplicates 113 

 samples have been received and analyzed. Of these, fifteen 

 represent unmixed raw materials including ground bone 

 and tankage. 



The fertilizers, in general, met their guarantee. In a few 

 instances marked shortages have occurred in some one ele- 

 ment, but against these in most cases have been an excess 

 of some other constituent. The consumer now is concerned 

 more about the nature of the guarantee rather than about 

 the deficiencies. The manufacturers are anxious to have 

 all goods meet the guarantee. Any notable deviation is 

 generally due to accident or mistake. 



The large number of brands offered for sale give the con- 

 sumer considerable latitude in the choice of goods. The 

 manufacturers are advocating the use of the better grades 

 of fertilizers. This is a step in the right direction and 

 should be taken advantage of by the consumer. With a 

 given sum of money more plant food may be purchased in 

 the form of high-grade fertilizers. 



Messrs. J. E. Robinson and D. B. Keyes have assisted in 

 the preparation of the following analytical results. 



The samples on which these results have been determined 

 will be kept for three months after the distribution of this 

 report.
