The Fertilizer Inspection in 1901 



In accordance with the public statutes, samples of the dif- 

 ferent brands of fertilizers, licensed to be sold in this state, 

 -were collected under the supervision of the secretary of the 

 .:State Board of Agriculture, Hon. N. J. Bachelder. The 

 analyses of the samples were made at the New Hampshire 

 'College Agricultural Experiment Station, under the direction 

 •of its chemist, Mr. F. W. Morse. Mr. W. L. Barker of the 

 New Hampshire College assisted in collecting the samples, 

 and Messrs. H. A. Clark, W. W. Braman, and A. L. Sulli- 

 van performed the analytical work. One hundred and six 

 brands of fertilizers were collected and analyzed. Four of 

 these brands only were deficient in their composition to such 

 an extent as to lower their valuation below that guaranteed. 

 In other cases there were deficiences in one constituent, but 

 small enough to be offset by excesses in other constituents. 

 Potash and available phosphoric acid were the constituents 

 which were oftenest deficient, but almost always only one 

 of these was below the guarantee in any one fertilizer, and 

 this deficiency was made up by an excess of the other ; that 

 is, if potash was found to be lower than the guarantee, avail- 

 able phosphoric acid proved to be higher.
