FERTILIZER ANALYSES GUARANTEES vs. 

 INSPECTION DETERMINATIONS 



Fertilizer inspections are made each year by the New Hampshire 

 Agricultural Experiment Station for the State Department of Agricul- 

 ture. An annual report is issued which is available to all farmers upon 

 request. Thus, any farmer may revie^\■ the findings on all brands and 

 analyses. Such a review should be of value in considering purchases. 



On the average, guarantees have been more than met. For the eight 

 years 1936-1943, covering inspections of complete fertilizers, the aver- 

 age amounts of chemicals as sho^^■n by determinations exceeded guaran- 

 tees as follows: nitrogen -|- 1.4 per cent, available phosphoric acid +2.4 

 per cent, water soluble potash + -•- per cent. (See Table 5 -A.) 



However, in 46 per cent of these cases, guarantees were not fully 

 met. Approximately 3 3 per cent were deficient in one chemical, 12 per 

 cent in two chemicals, and one per cent in three chemicals. (See Table 

 5-B covering each of the eight years.)

* Brand refers to a specific analysis of a given company. That is, 5-8-7 and 5-10-10 offered by 

 Company A and B would be two different brands.
