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. 



Control officials are giving the matter of excessive ash in sheep and cattle manure 

 samples their attention. Total ash was determined in each of the 17 samples of dried 

 manure drawn this year. The percent ash found varied from 1.31% to 50.85% Excessive 

 ash content is indicated when the amount is over 30% and adulteration with sand or 

 "dirt" is likely. Even with high ash content the guarantees are usually met because the 

 amount of plant food in manures is relatively small. The point is that manures are 

 bought to supply a considerable amount of organic matter. A high ash content indicates 

 a relatively low organic matter content. This problem is being given special attention by 

 New England control officials. 



USE OF COMMERCIAL FERTILIZERS 



It is not within the scope of this department to make recommendations regarding 

 the use of commercial fertilizers. The Department of Agronomy and the Department 

 of Biochemistry 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 dis- 

 tribution to residents of New Hampshire. Address your request to Mail Service, Uni- 

 versity of New Hampshire, Durham, New Hampshire. A list of currently available
