State Services 



Inspection of Fertilizers and Feetlingstuffs 



Official samples of fertilizers and feedingstuffs as submitted by the State 

 Department of Agriculture have been analyzed. 



Fertilizers: Of 173 samples submitted, 108 met the guarantee in all re- 

 spects. Analysis for nitrogen, phosphoric acid, potash, total magnesium, water 

 soluble magnesium, and boron were made when guarantees for these materials 

 were made. Penalties were assessed by the State Department of Agriculture 

 on 27 different lots of fertilizers. The manufacturers in general are doing a 

 good job in supplying the plant nutrient needs of New Hampshire farmers 

 and home owners. Detailed analyses of these samples are published in Bulle- 

 tin 446 of this Station. 



Feeds: A total of 703 official samples of feedingstuffs were submitted for 

 analysis. Of these, 78 were pet foods, mostly canned cat and dog foods. 

 Guarantees were generally met and when deficiencies occurred they were 

 usually slight. Only 10.4 percent were deficient in protein, 5.9 percent were 

 deficient in fat, and 7.1 percent carried an excess of crude fiber. Of the 

 samples analyzed, 75 were from bulk delivery lots and 120 were drawn on 

 New Hampshire farms. Also 83 mixed feed or ingredients and 30 pet food 

 lots were found to be unregistered at the time of sampling. Detailed results 

 are published in Bulletin 450.
