be determined only by a chemical analysis. To insure that they are 

 being furnished by all manufacturers 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 proved by chemical analysis, the prose- 

 cution or seizure provisions of the law may be invoked. The pur- 

 chaser's refusal to buy a fertilizer which does not conform to the law 

 in every respect will not only assist in the enforcement of the law but 

 will at the same time insure himself the protection of the law. If the 

 buyer fails to assure himself the legal requirements have been met, he 

 accepts the fertilizer at his own risk. 



Use of Commercial Fertilizers 



This bulletin is concerned with the enforcement of the fertilizer 

 law. It is not within its scope to make recommendations regarding 

 the use of commercial fertilizers. The Department of Agronomy and 

 the Department of Agricultural and Biological Chemistry of the Uni- 

 versity of New Hampshire Agricultural Experiment Station are con- 

 stantly testing soils and carrying out experimental work with various 

 fertilizer materials on hay and crop land. The Department of Horti- 

 culture does considerable experimenting to determine the best fertili- 

 zer treatments for fruits and vgetables. Much of this work has been 

 published, and is available for free distribution to residents of New 

 Hampshire. Address your request to Mailing Room, University of 

 New Hampshire, Durham, New Hampshire.
