that they are being furnished by 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 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 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 that 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 University of New Hampshire Agricultural 

 Experiment Station test soils and conduct experimental work with various fer- 

 tilizer materials on hay and crop land. The Department of Horticulture inves- 

 tigates fertilizer treatments for fruits and vegetables. Much of this work has 

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

 shire. Address your request to Mail Service, University of New Hampshire, 

 Durham, New Hampshire.
