of these constituents can be determined only by a chemical analysis. To insure 

 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 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 him the protection of the law. If the buyer fails to 

 assure himself that the legal requirements have been met, he accepts the fer- 

 tilizer at his own risk. 



USE OF COMMERCIAL FERTILIZERS 



It is not within the scope of this bulletin to make recommendations regard- 

 ing 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 fertilizer materials on hay and crop land. The Department 

 of Horticulture investigates fertilizer treatments for fruits and vegetables. 

 Much of this work has been published, and is available for free distribution to 

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

 of New Hampshire, Durham, New Hampshire.
