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 prosecution or seizure provisions of the law may 

 be invoked. The pui'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 Depai'tment of Agricultural 

 and Biological Chemistry of the University of New Hampshire Agricultural Ex- 

 periment Station test soils and conduct experimental work with various fertilizer 

 materials on hay and crop land. The Department of Horticulture does consider- 

 able experimenting to determine the best fertilizer treatments for fruits and 

 vegetables. Much of this work has been published, and is available for free distri- 

 bution to residents of New Hampshire. Address your request to Mail Service, 

 University of New Hampshire, Durham, New Hampshire.
