pounds of fertilizer in the package, the name, brand or 

 trademark under which the fertilizer is sold, the name 

 and address of the manufacturer or importer, the loca- 

 tion of the factory, and a chemical analysis stating the 

 minimum percentage of nitrogen, of available phosphoric 

 acid and of water soluble potash expressed in whole num- 

 bers. 



"No fertilizer or fertilizer material containing the three 

 essential fertilizing elements, nitrogen, phosphoric acid 

 and potash may be sold or offered for sale if the total 

 minimum plant food nutrients contained therein is less 

 than fourteen per cent by weight, provided however that 

 natural animal and bird manures shall be excepted from 

 the provisions of this section." 



The state official charged with the enforcement of the 

 fertilizer law is the Commissioner of Agriculture. Copies 

 of the full text of the law may be obtained from his of- 

 fice in Concord. All inquiries concerning the law and all 

 matters relative to the registration of brands should be 

 addressed to his office. 



The chief purpose of the official inspection required by 

 the fertilizer law is to protect the consumer against the 

 misbranded products which would doubtless soon appear 

 on the market if the sale of fertilizer was not under state 

 regulation. The value of a fertilizer depends mainly upon 

 its content of available plant food, particularly nitrogen, 

 phosphoric acid and potash. The presence of these con- 

 stituents can only be determined by a chemical analysis. 

 To insure that they are being furnished by all manu- 

 facturers in the guaranteed amounts, it is considered 

 necessary that each brand of fertilizer offered for sale be 

 officially inspected and analyzed one or more times each 

 year. When failure to meet the guarantee is proven by 

 chemical analysis, the prosecution or seizure provisions 

 of the law may be invoked. The purchaser's refusal to 

 buy a fertilizer which does not conform to the law in 

 every respect will not only assist in the enforcement of
